BSC 2085C Lecture Notes - Lecture 12: Subclavian Vein, Lymphatic Vessel, Extracellular Fluid
Document Summary
Lymphatic organs: thymus, spleen, tonsils, lymphatic nodes and nodules. Lymph: a clear (except for lymph coming out of digestive tract), complex, watery appearing fluid; closely resembles blood plasma (because it was blood plasma) in a composition with a lower percentage of protein. Interstitial fluid (extracellular): a complex fluid that fills the spaces between or around the cells; resembles blood plasma (because it was blood plasma) in a composition with a lower percentage of protein. Lymphatic vessels: consists of lymphatic capillaries and veins. More valves in lymphatic veins than blood veins, which is needed for extremely low pressure. Lymph is transported through progressively bigger vessels, through lymph nodes, until it reaches the subclavian veins. Larger lymphatic vessels contain one-way valves and smooth muscle: the green is overlapped endothelial cells, which is unique. The basement membrane of lymphatic capillaries is arranged in a way that from anchoring filaments. They anchor the capillary in place, so lymphatic capillary doesn"t curl up.
