the heart
- superior/inferior vena cava deliver
deox blood to right atrium through
the semilunar valves to prevent back
flow of blood back into the veins
- when filled with blood thin atrium walls
contract due to the low pressure and
forces the blood into the right ventricle
through the tricuspid valve (AV) as
pressure is high in the atrium and to
separate the atrium and ventricle and to
prevent back flow of blood into the atrium
- tough tendinous cords prevent valves
from turning inside out due to the
pressure when ventricles contract
- when ventricles contract blood flows to
the pulmonary artery through the SL valve,
the blood collects O2 from the lungs and
return throughout the pulmonary vein
- blood flows at low pressure into the left
atrium which contracts forcing blood into
the left ventricle through the bicuspid valve
- the thick muscular wall in the left ventricle contracts
building pressure allowing blood to flow to the rest of the
body through the aortic valve preventing back flow into the
ventricle
