BIOL 212 Lecture Notes - Lecture 6: Lymphatic Vessel, Extracellular Fluid, Lacteal
Document Summary
Lecture #6: the lymphatic system: main function. Maintains body fluid level: a. fluid lost at capillaries returned to blood, 2. Fat (& fat-soluble vitamin) absorption: a. lacteal in intestines, 3. Protection against infections lymphocytes/ monocytes: maintains body fluid level, recirculate fluid lost at capillaries back into blood (blood vessels) plasma --> (tissue) interstitial fluid --> (lymphatic vessels) lymph, lymphedema (edema) , 1. Disruption in re-circulation by lymphatic vessels or nodes of interstitial fluid: 2. Causes of edema: reduced concentration of plasma proteins, blockage of lymph vessels (filarial worm) Secondary cause: removal of vessels/lymph nodes after cancer, lacteal, 1. Able to absorb fats & fat-soluble vitamins, within lymph: 4. Blind end tubes intertwine with blood capillaries: 2. Fluid from tissue builds up and moves into lymphatic capillaries: 3. Fluid in lymphatic capillaries (lymph) moves up one way toward lymphatic vessels: lymphatic vessels, 1. Lymphatic capillaries combine to form lymphatic vessels: 2. Lymphatic vessels travel with blood vessels: 3.
