ANAT 103 Lecture Notes - Lecture 22: Subclavian Vein, Lymph Node, Thoracic Duct
Document Summary
Consists of lymph fluid, lymphatic vessels, lymphatic tissue and bone marrow. Begin as lymphatic capillaries located between cells. The capillaries merge and form the vessels w/ thin walls and numerous valves. Lymph flows through the lymph nodes (bean shape organs w/ b and t cells) along the vessels and into lymph trunks (lumbar, intestinal, bronchomediastinal, subclavian adn jugular) Travels from the lymph trunks to either the thoracic duct or the right lymphatic duct and then into venous blood. Left side: thoracic duct begins at the cisterna chyli, cistera gets lymph from the left upper body and entire body after the ribs, drains lymph into the left internal jugular and left subclavian veins. Right side: right lymphatic duct receives lymph from upper right side of body, drains into the right internal jugular and right subclavian veins. Excess fluid drains into the lymph vessels to become lymph. Intersitial fluid lymph capillaries lymph vessels lymph trunks lymph ducts internal jugular or subclavian veins.
