Chapter 22 Assessing Peripheral Vascular System Arteries Carry oxygenated, nutrient-rich blood from the heart to the capillaries The arterial network is a high-pressure system. Blood is propelled under pressure from the left ventricle of the heart . Major arteries of arm: brachial, radial, ulnar Major arteries of the leg: femoral, popliteal, dorsalis pedis, posterior tibial Question : Arteries carry deoxygenated, nutrient-depleted, waste-laden blood from the tissues back to the heart . —— False. Veins carry deoxygenated, nutrient-depleted, waste-laden blood from the tissues back to the heart. Arteries carry oxygenated, nutrient-rich blood from the heart to the capillaries . Veins Carry deoxygenated, nutrient-depleted, waste-laden blood from the tissues back to the heart Low -pressure system — no force propelling blood flow Three types of veins: deep veins, superficial veins, and perforator veins Femoral, popliteal, saphenous veins Deep, superficial, and perforator veins all contain one-way valves . Lymphatic System Lymphatic capillaries, lymphatic vessels, lymph nodes Capillaries and fluid exchange
Small blood vessels Form the connection between the arterioles and venules Allow the circulatory system to maintain vital equilibrium Deep Vein Thrombosis: Risk Factors Reduced mobility Dehydration Increased viscosity of the blood Venous stasis Risk Factors for Lower Extremity ( Peripheral artery disease ) PAD
