KIN 272 Chapter Notes - Chapter 20: Reticular Connective Tissue, Lymphatic System, Thoracic Duct
Document Summary
Chapter 20 the lymphatic system and lymphoid organs and tissues. Lymphatic vessels, lymph nodes, and lymph make up the lymphatic system. Lymphatic vessels return fluids that have leaked from the blood vascular system back to the blood. Lymphoid organs and tissues protect the body by removing foreign material from the lymph and bloodstream, and provide a site for immune surveillance. 20. 1 the lymphatic system includes lymphatic vessels, lymph, and lymph nodes. Lymphatic vessels form a one-way network - lymphatic capillaries, collecting vessels, trunks, and ducts - in which fluid flows only toward the heart. The right lymphatic duct drains lymph from the right arm and right side of the upper body. The thoracic duct receives lymph from the rest of the body. These ducts empty into the blood vascular system at the junction of the internal jugular and subclavian veins in the neck. Lymphatic capillaries are exceptionally permeable, admitting proteins and particulate matter from the interstitial space.
