is the aortic semilunar valve oxygenated or deoxygenated?
Receives deoxygenated blood from the vena cavae and coronary sinus and empties it into the right ventricle. Pumps oxygenated blood into the aorta via the tricuspid aortic valve; also forms the apex of the heart. Pumps deoxygenated blood into the pulmonary trunk via the pulmonary valve.
