The Lymphatic System By: Camden McMinn

Lymph Vessels: Carry lymph, walls are permeable to allow increase in size. Central Lymphoid Tissues: – Bone Marrow- Produces all pluripotent lymphoid cells in adults and helps in distinction of B-Lymphocytes. – Thymus- Helps in differentiation of T-Lymphocytes Peripheral Lymphoid Organs: – Lymph Node- Small nodules of lymphoid tissue that purify the lymph. Found in the smaller lymph vessels. – Spleen- Removes old blood cells and keeps a reserve of blood in case of emergency. Synthesizes antibodies. – Epitheliolymphoid tissues- Lymphoid nodules that work as security against all incoming factors. Located in alimentary canal and respiratory tracts. Lymphocytes: Mature B- and T-Lymphocytes that protect the body from infectious factors in the blood. Components

Function of the system The lymphatic system: – Removes certain matter from the blood stream – Produces lymphocytes – Generates immune responses

Contribute to the Body The lymphatic system sends lymph fluid throughout the entire body which helps fight infection. When there is infection in the body it would raise your temperature causing a fever. Any infection or malfunction can throw of normal processes which affect homeostasis. Without the lymphatic system, your body couldn’t fight against infection. It works together with the immune system to aid in the removal of negative substances such as cancer cells, toxins, waste, dead blood cells, etc.
