pulmonary circuit
pathway between heart & lungs
-delivers blood to lungs
function of pulmonary circuit
to allow blood to pick up o2 and get rid of co2 at the lungs (specifically the pulmonary capillaries)
how does deoxygenated blood return to the right atrium
moves from body organs via. the superior and inferior vena cava.
what happens when the blood returns too the right atrium
right atrial systole
right atrial systole
contracts, pumping deoxygenated blood into the right ventricle via the tricuspid valve (valve)
tricuspid valve
heart valve between the right atrium & right ventricle
right ventricular systole
deoxygenated blood in the right ventricle is pumped out of the heart into the pulmonary arteries via semilunar valves
semilunar valves
valve between the ventricle and pulmonary arteries
pulmonary arteries
delivers blood to the lungs
deoxygenated blood at lungs
gas exchange occurs
co2 is exchanged to o2 turning blood oxygenated
oxygenated blood
goes to left atrium via going through pulmonary veins
