PPT-The Lymphatic System and Immunity

Chapter 13 The Lymphatic System THE LYMPHATIC SYSTEM Lymph fluid in the tissue spaces that carries protein molecules and other substances back to the blood Lymphatic vessels permit only oneway movement of lymph. 1) Lymphatic Vessels. . Reach every organ in the body. . . Pick up the tissue fluid (lymph) and transport it to the heart. Lymph Nodes. . Pea shaped tissue along the vessels that contain compartment sinuses that house lymphocytes and macrophages. Introduction. Network of vessels that circulates fluid. Transport fluid from interstial space in most tissues and returns it to the blood stream. Absorbs fat in the small intestines. Defends the body against disease-causing agents. Lymphatic System. & . Immunity. Lymphatic System Components. supplement to the circulatory system.. Contains:. . Lymph. . Lymph nodes. . Lymph vessels. . in the . . intestinal tract. . Tonsils. -Consists of: Lymph, lymph vessels, lymph nodes and lymphatic tissue. -System works in conjunction with the circulatory system to remove waste and excess fluids from the tissues. -Lymph-a thin watery fluid composed of intercellular and interstitial fluid which forms when plasma diffuses into the tissue spaces. .

The lymphatic system aids the immune system in removing and destroying waste, debris, dead blood cells, pathogens, toxins, and cancer cells. . Functions of Lymphatic System. Help protect body from infection by disease causing agents. Must . detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue..
