Document Summary
Drains excess interstitial fluid: collects fluid from between tissues/cells and returns it to the blood, blockage impairs drainage= huge elephant size edema in interstium of cells. Transports dietary lipids: transports lipids (fats) and lipid-soluble vitamins (a, d, e, k) from the intestines to the blood. Carries out immune responses: initiates responses directed against pathogens. Picks up leaked proteins and returns them to bloodstream. Lose fluid and proteins from plasma to interstium. Some will re-enter capillaries but the extra go into lymphatic capillaries. Interstitial vessels to larger and larger lymphatic vessels along which are scattered lymph nodes. To the keep lymph moving in the right direction there are valves in vessels. Vessels unite to form lymph trunks: lumbar, intestinal, bronchomediastinal, subclavian. Trunks drain into two main ducts: thoracic duct (left lymphatic, right lymphatic duct. Junction of r internal jugular and subclavian veins: short duct (1. 2cm) drains upper-right side of head and upper limp.
