Document Summary
Pumping of heart makes this a high-pressure system. Each heartbeat creates pressure wave, making arteries expand and recoil. All arteries have this pressure wave, or pulse, throughout their length. Palpated in groove between sternomastoid muscle and trachea. Below elbow, brachial artery bifurcates into ulnar and radial arteries arches: runs distally and form two arches supplying hands; called super cial and deep palmar. Ulnar artery is deeper and often dif cult to palpate. Major artery is femoral artery, which travels down the thigh. At lower thigh, courses posteriorly termed popliteal artery. Anterior tibial artery travels down front of leg to dorsum of foot dorsalis pedis artery. In back of leg, posterior tibial artery travels down medial malleolus and in foot divides into. Function of arteries is to supply oxygen and nutrients to tissues. Ischemia is de ciency in supply of oxygenated arterial blood, caused by obstruction of blood plantar arteries vessel. Body has more veins, lies closer to skin surface.
