To trace: The pathway of blood from the placenta to the fetus and back to the placenta. Introduction: Cardiovascular system refers to the circulatory system of an individual. It includes the heart, blood, and blood vessels (arteries, capillaries, and veins). Blood circulates within the blood vessels and supply nutrients to the body. There are two circuits (pulmonary and systemic) in the mammals. The blood in the fetus does not get oxygenated in the lungs; instead it gets oxygenated in the placenta. Pictorial representation: Fig.1:Pathway of fetal blood. Fig.1:Pathway of fetal blood.
