Context: Hummingbirds are birds from the Americas that constitute the family Trochilidae. They are among the smallest of birds, most species measuring . Indeed, the smallest extant bird species is a hummingbird, the 5-cm bee hummingbird weighing less than a U.S. penny (2.5 g)., The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. The heart is located between the lungs, in the middle compartment of the chest.
In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the "right heart" and their left counterparts as the "left heart". Fish in contrast have two chambers, an atrium and a ventricle, while reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium.
The heart pumps blood with a rhythm determined by a group of pacemaking cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node and along the conduction system of the heart. The heart receives blood low in oxygen from the systemic circulation, which enters the right atrium from the superior and inferior venae cavae and passes to the right ventricle. From here it is pumped into the pulmonary circulation, through the lungs where it receives oxygen and gives off carbon dioxide. Oxygenated blood then returns to the left atrium, passes through the left ventricle and is pumped out through the aorta to the systemic circulationwhere the oxygen is used and metabolized to carbon dioxide. The heart beats at a resting rate close to 72 beats per minute. Exercise temporarily increases the rate, but lowers resting heart rate in the long term, and is good for heart health.
Cardiovascular diseases (CVD) are the most common cause of death globally as of 2008, accounting for 30% of deaths. Of these more than three quarters are a result of coronary artery disease and stroke. Risk factors include: smoking, being overweight, little exercise, high cholesterol, high blood pressure, and poorly controlled diabetes, among others. Cardiovascular diseases frequently have no symptoms or may cause chest pain or shortness of breath. Diagnosis of heart disease is often done by the taking of a medical history, listening to the heart-sounds with a stethoscope, ECG, and ultrasound. Specialists who focus on diseases of the heart are called cardiologists, although many specialties of medicine may be involved in treatment., Dinosaurs are a diverse group of animals of the clade Dinosauria that first appeared during the Triassic. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago. They became the dominant terrestrial vertebrates after the TriassicJurassic extinction event 201 million years ago. Their dominance continued through the Jurassic and Cretaceous periods and ended when the CretaceousPaleogene extinction event led to the extinction of most dinosaur groups 66 million years ago., Australasia, a region of Oceania, comprises Australia, New Zealand, the island of New Guinea, and neighbouring islands in the Pacific Ocean. Charles de Brosses coined the term (as French "Australasie") in "Histoire des navigations aux terres australes" (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific (Magellanica). The bulk of Australasia sits on the Indo-Australian Plate, together with India., Birds (Aves), also known as avian dinosaurs, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds., The ear is the organ of hearing and, in mammals, balance. In mammals, the ear is usually described as having three partsthe outer ear, middle ear and the inner ear. The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word "ear" often refers to the external part alone. The middle ear includes the tympanic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contains structures which are key to several senses: the semicircular canals, which enable balance and eye tracking when moving; the utricle and saccule, which enable balance when stationary; and the cochlea, which enables hearing. The ears of vertebrates are placed somewhat symmetrically on either side of the head, an arrangement that aids sound localisation., The Australian magpie ("Cracticus tibicen") is a medium-sized black and white passerine bird native to Australia and southern New Guinea. Although once considered to be three separate species, it is now considered to be one, with nine recognised subspecies. A member of the Artamidae, the Australian magpie is classified in the butcherbird genus "Cracticus" and is most closely related to the black butcherbird ("C. quoyi"). It is not, however, related to the European magpie, which is a corvid. The adult Australian magpie is a fairly robust bird ranging from in length, with distinctive black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, and can be distinguished by differences in back markings.The male has pure white feathers on the back of the head and the female has white blending to gray feathers on the back of the head. With its long legs, the Australian magpie walks rather than waddles or hops and spends much time on the ground., The beak, bill, or rostrum is an external anatomical structure of birds that is used for eating and for grooming, manipulating objects, killing prey, fighting, probing for food, courtship and feeding young. The terms "beak" and "rostrum" are also used to refer to a similar mouth part in some dicynodonts, Ornithischians, cephalopods, cetaceans, billfishes, pufferfishes, turtles, Anuran tadpoles and sirens., The black - backed butcherbird ( Cracticus mentalis ) is a species of bird in the family Artamidae . It is found in Papua New Guinea , Indonesia , and northern Queensland in Australia ., Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones). Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 64,000 species described. Vertebrates include the jawless fish and the jawed vertebrates, which include the cartilaginous fish (sharks and rays) and the bony fish. , An endotherm (from Greek  "endon" "within" and  "therm" "heat") is an organism that maintains its body at a metabolically favorable temperature, largely by the use of heat set free by its internal bodily functions instead of relying almost purely on ambient heat. Such internally generated heat is mainly an incidental product of the animal's routine metabolism, but under conditions of excessive cold or low activity an endotherm might apply special mechanisms adapted specifically to heat production. Examples include special-function muscular exertion such as shivering, and uncoupled oxidative metabolism such as within brown adipose tissue.
Only birds and mammals are extant universally endothermic groups of animals. Certain lamnid sharks, tuna and billfishes are also endothermic., A songbird is a bird belonging to the clade Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as a scientific or vernacular name is Oscines, from Latin "oscen", "a songbird". This group contains some 4,000 species found all over the world, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song., Currawongs are three species of medium-sized passerine birds belonging to the genus "Strepera" in the family Artamidae native to Australasia. These are the grey currawong ("Strepera versicolor"), pied currawong ("S. graculina"), and black currawong ("S. fuliginosa"). The common name comes from the call of the familiar pied currawong of eastern Australia and is onomatopoeic. They were formerly known as crow-shrikes or bell-magpies. Despite their resemblance to crows and ravens, they are only distantly related to the corvidae, instead belonging to an Afro-Asian radiation of birds of superfamily Malaconotoidea., A passerine is any bird of the order Passeriformes, which includes more than half of all bird species. A notable feature of passerines compared to other orders of Aves is the arrangement of their toes, three pointing forward and one back, which facilitates perching. Sometimes known as perching birds or, less accurately, as songbirds, the passerines form one of the most diverse terrestrial vertebrate orders, with over 5,000 identified species. It has roughly twice as many species as the largest of the mammal orders, the Rodentia. It contains more than 110 families, the second-most of any order of tetrapods (after Squamata, the scaled reptiles).
The passerines contain several groups of brood parasites such as the viduas, cuckoo-finches, and the cowbirds. Most passerines are omnivorous, while the shrikes are carnivorous., The ostrich or common ostrich ("Struthio camelus") is either one or two species of large flightless birds native to Africa, the only living member(s) of the genus "Struthio", which is in the ratite family. In 2014, the Somali ostrich ("Struthio molybdophanes") was recognized as a distinct species., Peltops is a genus of bird in the family Artamidae. The genus contains two species endemic to the island of New Guinea. The genus was once placed with the monarch flycatchers, but molecular and morphometric studies place it closer to the butcherbirds, possibly as a sister taxon to this group. The genus is named for the Greek "pelte" meaning small shield and "ops" meaning face. The species have also had the common name of shieldbill., The Cracticinae, bellmagpies and allies, gathers together 12 species of mostly crow-like birds native to Australasia and nearby areas., Butcherbirds are magpie-like birds in the genus "Cracticus." They are native to Australasia. The Australian magpie has recently been placed in the same genus, and this new taxonomy has been supported by recent phylogenetic analyses. Together with three species of currawong and two species of peltops, butcherbirds and the Australian magpie form the subfamily Cracticinae in the family Artamidae., The superclass Tetrapoda (Ancient Greek s tetrapods, "four-footed"), or the tetrapods , comprises the first four-limbed vertebrates and their descendants, including the living and extinct amphibians, birds, mammals, reptiles and some ancient, exclusively aquatic creatures such as the Acanthostega. Tetrapods evolved from the lobe-finned fishes around 390 million years ago in the middle Devonian Period, with modern tetrapod groups having appeared by the late Devonian, 367.5 million years ago. The specific aquatic ancestors of the tetrapods, and the process by which land colonization occurred, remain unclear, and are areas of active research and debate among palaeontologists at present., Feathers are epidermal growths that form the distinctive outer covering, or plumage, on birds. They are considered the most complex integumentary structures found in vertebrates, and indeed a premier example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups., New Guinea (or, historically, "") is a large Island in the South West Pacific region., The bee hummingbird, zunzuncito or Helena hummingbird ("Mellisuga helenae") is a species of hummingbird., Subject: black-backed butcherbird, Relation: instance_of, Options: (A) 12 (B) animal (C) bee (D) bell (E) bill (F) bird (G) cause (H) chest (I) class (J) complex (K) event (L) extinct (M) extinction (N) family (O) fish (P) fluid (Q) food (R) four (S) genus (T) group (U) health (V) hearing (W) history (X) humans (Y) india (Z) island ([) killing (\) may (]) medicine (^) member (_) nine (`) ocean (a) organ (b) organism (c) period (d) plate (e) process (f) production (g) range (h) rank (i) region (j) research (k) result (l) shield (m) side (n) size (o) skeleton (p) song (q) species (r) system (s) taxon (t) taxonomy (u) temperature (v) three (w) two

Context: Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking, deep growling vocals and screams, aggressive, powerful drumming featuring double kick or blast beat techniques, minor keys or atonality, abrupt tempo, key, and time signature changes and chromatic chord progressions. The lyrical themes of death metal may invoke slasher film-stylized violence, religion (sometimes Satanism), occultism, Lovecraftian horror, nature, mysticism, mythology, philosophy, science fiction, and politics, and they may describe extreme acts, including mutilation, dissection, torture, rape, cannibalism, and necrophilia., Melodic death metal (also referred to as melodeath or MDM) is a subgenre death metal that employs highly melodic guitar riffs, often borrowing from traditional heavy metal. The style originated and developed in Sweden (pioneered by At the Gates, Dark Tranquillity and In Flames) and the United Kingdom (pioneered by Carcass) during the early and mid-1990s. The Swedish death metal scene did much to popularize the style, soon centering in the "Gothenburg metal" scene., Alexi "Wildchild" Laiho (born Markku Uula Aleksi Laiho; 8 April 1979) is a Finnish guitarist, composer, and vocalist. He is best known as the lead guitarist, lead vocalist and founding member of the melodic death metal band Children of Bodom, and is also the guitarist for Sinergy and Kylähullut. He has previously played with Thy Serpent and Impaled Nazarene on occasion, as well as Warmen and Hypocrisy., Daniel Freyberg is a heavy metal guitarist and vocalist for the band Naildown and the guitarist for Children of Bodom. He is the former guitarist for Norther. , Lead guitar is a guitar part which plays melody lines, instrumental fill passages, guitar solos, and occasionally, some riffs within a song structure. The lead is the featured guitar, which usually plays single-note-based lines or double-stops.
In rock, heavy metal, blues, jazz, punk, fusion, some pop, and other music styles, lead guitar lines are usually supported by a second guitarist who plays rhythm guitar, which consists of accompaniment chords and riffs., Rhythm guitar is a technique and role that performs a combination of two functions: to provide all or part of the rhythmic pulse in conjunction with singers or other instruments; and to provide all or part of the harmony, i.e. the chords, where a chord is a group of notes played together. Therefore, the basic technique of rhythm guitar is to hold down a series of chords with the fretting hand while strumming rhythmically with the other hand. More developed rhythm techniques include arpeggios, damping, riffs, chord solos, and complex strums., Hatebreeder is the second studio album by Finnish metal band Children of Bodom . In it , the band explores a classically influenced sound . It also carries some influence from neoclassical metal , in the fast riffs and complex soloing style . This record contains concert favorites such as `` Silent Night , Bodom Night '' and `` Downfall '' . The keyboards show more presence on this album , with longer and more elaborate solos than in their previous work . The `` Deluxe Edition '' was released in 2005 with bonus material . Hatebreeder was also re-released in 2008 . The band 's self - titled song was re-recorded as the second - to - last track for this album . This was the first album with guitars in D tuning ( D , G , C , F , A , D ) after Something Wild , which was in C  tuning ( C  , F  , B , E , G  , C  ) ., Children of Bodom is a melodic death metal band from Espoo, Finland. Formed in 1993, the group currently consists of Alexi Laiho (vocals, lead guitar), Janne Wirman (keyboards), Henkka Seppälä (bass), Jaska Raatikainen (drums) and Daniel Freyberg (rhythm guitar). In total they have released nine studio albums, two live albums, two EPs, two compilation albums and one DVD., Subject: hatebreeder, Relation: genre, Options: (A) basic (B) blues (C) death metal (D) fusion (E) heavy metal (F) heavy metal music (G) horror (H) instrumental (I) jazz (J) melodic death metal (K) mythology (L) nature (M) philosophy (N) politics (O) rhythm (P) rock (Q) song

Context: Herbert Chapman (19 January 1878  6 January 1934) was an English association football player and manager. Though he had an undistinguished playing career, he went on to become one of the most successful and influential managers in early 20th-century English football, before his sudden death in 1934., Joseph Dorville `` Joe '' Walter ( 16 August 1895 -- 23 May 1995 ) was a professional footballer , who played for Bristol Rovers , Huddersfield Town , Taunton United and Bath City . He was the last surviving player to play under Herbert Chapman while at Huddersfield . Walter 's early footballing experience came while serving in the Gloucestershire Regiment during the First World War , when he represented the Third Battalion of the Glorious Glosters , before joining Horfield United in the Horfield area of his home city of Bristol . After a year playing in the Bristol and Suburban Association Football League , he joined his first professional team in 1919 when he signed for Bristol Rovers . Later in life he worked as a groundsman , firstly for the Bristol Co-Operative Society , before taking responsibility for Bristol City 's Ashton Gate pitch in 1955 . He was later appointed as an assistant coach at his former club , Bristol Rovers , in 1960 when he was aged 65 . In Huddersfield 's final game at Leeds Road , against Blackpool on 30 April 1994 , he was the guest of honour . He was also present for Town 's visit to Bristol Rovers ' Twerton Park . On 5 November 1994 , he made English football history as he became the oldest living professional player at 99 years , on the death of former Brighton & Hove Albion player Zillwood March in his 102nd year ., South West England is one of nine official regions of England. It is the largest in area, covering and the counties of Gloucestershire, Bristol, Wiltshire, Somerset, Dorset, Devon and Cornwall, as well as the Isles of Scilly. Five million people live in South West England., Gloucester is a city and district in southwest England, the county city of Gloucestershire. Gloucester lies close to the Welsh border, on the River Severn, between the Cotswolds to the east and the Forest of Dean to the southwest., London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly., Association football, more commonly known as football or soccer, is a team sport played between two teams of eleven players with a spherical ball. It is played by 250 million players in over 200 countries and dependencies, making it the world's most popular sport. The game is played on a rectangular field with a goal at each end.
