Where does blood go after leaving the lungs of a mammal?
WebIn mammals, as in birds, the right and left ventricles of the heart are completely separated, so that pulmonary ( lung) and systemic (body) circulations are completely independent.

WebIt is then carried away by red blood cells. The blood leaving the lungs now has a high concentration of oxygen. It travels round the circulatory system to the cells in tissues and … WebApr 9, 2024 · Once blood is pumped out of the left ventricle and into the aorta, the aortic semilunar valve (or aortic valve) closes preventing blood from flowing backward into the left ventricle.
