adult blood circulation - Circulatory system - Wikipedia


Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. This is called the pulmonary circulation. The circulatory system of the blood is seen as having two components, a systemic circulation and a pulmonary circulation. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system.FMA: 7161.

Aug 01, 2005 · The fetal circulation (Fig. 1) is markedly different from the adult circulation. In the fetus, gas exchange does not occur in the lungs but in the placenta. The placenta must therefore receive deoxygenated blood from the fetal systemic organs and return its oxygen rich venous drainage to the fetal systemic arterial circulation.Cited by: 30. So the blood vessels of the body carry blood in a circle: moving away from the heart in arteries, traveling to various parts of the body in capillaries, and going back to the heart in veins. The heart is the pump that makes this happen. * picture of the heart and its parts * picture of the body and some of its organs. The Circulation of Blood.
