|---|---|---|---|---|---|
| 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.
