PPT-The Body’s Defenses The lymphatic System

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 organisms own healthy tissue. The lymphatic system consists of:. lymphatic vessels which drain excess fluid from the tissues and return it to the cardiovascular system. lymphatic organs such as lymph nodes, tonsils, spleen, thymus gland and red bone marrow that assist in immunity . -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. . a network of . vessels and organs that filters and returns interstitial fluid to blood circulation. .
