They, in turn, branch into a extremely large number of the smallest diameter vessels—the capillaries (with an estimated 10 billion in the average human body). Next blood exits the capillaries and begins its return to the heart via the venules.
Do all arteries carry oxygen rich blood?
Arteries carry blood away from the heart. In all but one case, arteries carry oxygen-rich blood. The exception is the pulmonary arteries. They carry oxygen-poor blood away from the heart, to the lungs, to pick up more oxygen.
How can you tell the difference between an artery and a vein?
Arteries are blood vessels responsible for carrying oxygen-rich blood away from the heart to the body. Veins are blood vessels that carry blood low in oxygen from the body back to the heart for reoxygenation.
What is the longest vein in the body?
Great Saphenous Vein (GSV) – The GSV is the large superficial vein of the leg and the longest vein in the entire body. It can be found along the length of the lower limb, returning blood from the thigh, calf, and foot to the deep femoral vein at the femoral triangle. The femoral triangle is located in the upper thigh.
