Heart and Blood Vessels

Blood flow to the legs, as is the case with any part of the body, is via the arteries and veins. Arteries carry oxygen-rich blood to the site, while veins transport oxygen-depleted blood away and back to the heart. Any excess fluid in the tissue spaces drains into the lymphatic vessels that eventually empties into the veins. Poor blood flow to the legs can be broadly termed as peripheral vascular disease (PVD). This includes any disease that impairs blood flow through the arteries or legs. However, the term has become synonymous with peripheral arterial disease (PAD) which is a problem with the blood flowing through an artery.
