Simply put, the circulatory system handles blood flow in the human body. Blood flow is necessary for the body's cells to get food and oxygen so they can function, and they also need to dump waste and carbon dioxide. The blood is the fluid that transports all these materials in both directions, and circulation of the blood is necessary to life. The heart acts as a pump for the system, and its regular contractions force blood through the vessels in the circulatory system. There are volumes of information on blood and on the circulatory system, and a link to the Wikipedia articles will get you started on your way to an understanding of this extraordinary biological system.

∙ 13y agoStarting in the right atrium, the blood flows through the tricuspid valve to the right ventricle. Here it is pumped out the pulmonary semilunar valve and travels through the pulmonary artery to the lungs. From there, blood flows back through the pulmonary vein to the left atrium. It then travels through the mitral valve to the left ventricle, from where it is pumped through the aortic semilunar valve to the aorta. The aorta forks, and the blood is divided between major arteries which supply the upper and lower body. The blood travels in the arteries to the smaller arterioles, then finally to the tiny capillaries which feed each cell. The (relatively) deoxygenated blood then travels to the venules, which coalesce into veins, then to the inferior and superior venae cavae and finally back to the right atrium where the process began.

After the Femoral artery the blood flow varries, unless you can give a more specific answer than "leg"
