Lymphatic System 13.1-13.3

TermDefinition
Lymphatic system and function Composed of lymphatic vessels and lymphatic organs. Functions: fluid balance, fat absorption, and defense (immune system)
Lymphatic vessels/capillaries Lymphatic tissue that absorbs excess tissue fluid.
Lymph The excess fluid that is absorbed by lymphatic vessels.
Ducts of lymphatic vessels Thoracic duct and right lymphatic duct. Theses ducts return tissue fluid back into the body.
Edema Swelling in lymphatic vessels as a result of the failure of the body to return tissue fluid back into the blood stream.
Immunity The ability to react to antigens so that the body remains free of disease.
Lymphatic organs (Primary) These organs contain large number of lymphocytes (white blood cells). The primary organs are red bone marrow and the thymus gland.
Red bone marrow A primary lymphatic organ found in vertebrae, end of long bones, the skull. These bones produce stem cells that differentiate into various white blood cells.
Thymus gland Located in chest. The role of the thymus is to be the location where T-lymphocytes mature. T-lymphocytes learn how to differentiate between self and non-self cells.
Secondary lymphatic organs Spleen, lymph nodes, tonsils
Spleen A secondary lymphatic organ what helps fight pathogens that are in the blood. Pathogens are killed as blood filters in the spleen.
Lymph nodes A round structure that contains B-lymphocytes and a sinus, surrounded by a capsule. When the lymph moves into the lymph node, B/T-lymphocytes kill pathogens.
Lymphatic nodules (tonsils) These tissues are not surrounded by capsules, but contain B/T-lymphocytes to aid in immunity. The tonsils are some of the first organs to react to pathogens.
Physical barriers of entry These barriers prevent pathogens from entering the body. They include the skin, mucous membranes, and ciliated cells.
Chemical barriers of entry Sebaceous secretions, saliva, tears, and normal flora.
