Life Science 2.3 The Lymphatic System
Objectives: Objectives: Describe the relationship between the lymphatic system and the cardiovascular system. Identify six parts of the lymphatic system, and describe their functions.
Vessels of the Lymphatic System Lymphatic system Group of organs and tissues that collect excess fluid and return it to your blood.
Lymph capillaries Smallest vessels of the lymphatic system. Lymph The fluid and particles absorbed into lymph capillaries.
Other Parts of the Lymphatic System Bone Marrow Soft tissue inside of bones. Where most red and white blood cells, including lymphocytes, are produced. Lymph Nodes Small, bean-shaped masses of tissue that remove pathogens and dead cells from the lymph.
Thymus Gland that produces T cells that are ready to fight infection. Spleen Largest lymphatic organ. Stores and produces lymphocytes.
Removes damaged red blood cells from circulatory system.
Produces white blood cells that fight infection.
Tonsils Lymphatic tissue in the nasal cavity and at the back of the mouth on either side of the tongue. Help defend the body against infection.
