Objectives:<br />Objectives:<br />Describe the relationship between the lymphatic system and the cardiovascular system.<br />Identify six parts of the lymphatic system, and describe their functions.<br />
Vessels of the Lymphatic System<br />Lymphatic system <br />Group of organs and tissues that collect excess fluid and return it to your blood.<br />

Other Parts of the Lymphatic System<br />Bone Marrow<br />Soft tissue inside of bones. <br />Where most red and white blood cells, including lymphocytes, are produced.<br />Lymph Nodes <br />Small, bean-shaped masses of tissue that remove pathogens and dead cells from the lymph.<br />
Thymus <br />Gland that produces T cells that are ready to fight infection.<br />Spleen <br />Largest lymphatic organ. <br />Stores and produces lymphocytes.<br /><ul><li>Red pulp
