Document Summary
Lymphatic system general overview: the lymphatic system is composed of lymph, lymph vessels, lymphatic tissues, and organs. It aids in bodily defenses: regulates interstitial fluid volume by returning materials back to the circulatory system, transports recently absorbed nutrients from the gut tube to the cardiovascular system. Malt (mucosal associated lymphatic tissue) in the small intestine. Lymph originates as interstitial fluid moving into lymphatic capillaries. Lymph is composed of water, dissolved solutes, and protein. Interstitial hydrostatic pressure pushes interstitial fluid into the lumen of lymphatic capillaries. Lymph flows into increasingly larger vessels, trunks, and ducts, ultimately emptying into the blood circulation via the subclavian vein. Lymphatic vessels contain valves that prevent pooling and backflow. Lymph is moved by the contraction of skeletal muscles there is no pump". Jugular trunk: subclavian trunk, brochomediastinal trunk, right lymphatic trunk. 2: drains the entirety of the right arm, upper right side of the thorax, and half of the face on the right side.
