the mammalian heart Flashcards
what are the components the heart
L atria
L ventricle
Aorta
R atria
R ventricle
Superior/inferior vena cava
pulmonary artery
pulmonary vein
coronary artery
chordae tendineae
myocardium
different valves
pulmonary valve
tricuspid
bicuspid
aortic valve
function of left atria
gets o2 blood from lungs and send to L ventricle
function of left ventricle
pump o2 blood to aorta to body
function of right atria
deoxygenated blood flows into this chamber via the superior and inferior vena cava
function of right ventricle
Contracts to pump oxygen-poor blood along the pulmonary arteries to the lungs
function of superior vena cava
receives blood from the head and arms and chest and empties into the right atrium of the heart
function of inferior vena cava
Brings deoxygenated blood from the lower portion of the body and into the right ventricle
function of Pulmonary Artery
carries deoxygenated blood from the right ventricle to the lungs
function of Pulmonary Valve
A semilunar valve between the right ventricle and the pulmonary artery
where and what is Tricuspid Valve
valve located between the right atrium and right ventricle
3 cusps
where and what is Aortic Valve
a semilunar valve between the left ventricle and the aorta
where and what is bicuspid
a valve that guards the opening between the left atrium and the left ventricle
function of Pulmonary Vein
vessel that carries oxygen-rich blood from the lungs to the heart
function of Coronary Artery
The artery that supplies heart tissue with blood
