NSE 13A/B Lecture Notes - Lecture 5: Deep Vein Thrombosis, Dorsalis Pedis Artery, Varicose Veins
Document Summary
Week 5 peripheral vascular and lymphatic system. Transport blood and lymph: vessels, oxygen and nutrients, waste products. Stretches and recoil: heartbeat creates a pressure wave. Pulses (temporal, carotid, brachial, radial, ulnar, femoral, popliteal, dorsalis pedis, posterior tibial) Temporal artery, carotid artery, and arteries in arms and legs. Jugular veins and veins in arms and veins in legs (deep and superficial veins in legs) Venous return: valves help with upward moving blood flow. Seen in calves, muscles contract to aid blood flow towards heart. Lymphatic vessels: retrieves excess fluid from tissues, returns it to blood. Lymph nodes: cervical: drain head and neck, axillary: drain breast and upper arm, epitrochlear: drains hand and lower arm. Inguinal nodes: drain external genitalia and anterior abdominal wall. Pregnant women: dependent edema and varicosities, hormonal changes cause vasodilation and drops blood pressure in first and second trimester.
