anatomy Flashcards
heart valves: identify the location and recognise the structural similarities and differences of the heart valves
where are the atrioventricular tricuspid and bicuspid valves locted
atrium → ventricle; try before you buy (on diagram; right to left in real life), so tricuspid between right atrium and right ventricle, and bicuspid between left atrium and left ventricle
what is the bicuspid valve also known as
mitral valve
is the mitral valve equally bicuspid
no
what type of valves are the pulmonary and aortic valves
semilunar tricuspid
where is the pulmonary valve located
right ventricle → pulmonary trunk
where is the aortic valve located
left ventricle → aortic trunk
what are chordae tendineae
“heart strings” which connect papillary (ventricular) muscles on myocardium to atrioventicular valves, holding them in place and preventing them turning inside-out
purpose of valves
ensure unidirectional flow down a pressure gradient; form the chamber below to the subsequent area when the chamber contracts
