Nursing-Lymphatic
| Lymphatic System | Contains lymph, lymphatic vessels, lymphoid organs, and lymphoid tissue |
| Lymphatic Vessels | Return tissue fluid to the blood |
| Lymphoid Tissue | Helps the body defense itself against disease |
| Lymph | A clear fluid that resembles plasma. Compose primarily of water, electrolytes, waste from metabolizing cells, and some protein that leaks out of the capillaries of the systematic circulation |
| Lymphatic Duct | Large tube or vessel that carries lymph, such as the thoracic duct; same as lymphatic vessel |
| Lymphoid Organs | Lymph nodes, tonsils, thymus gland, and spleen. Along with the tissue, helps defend the body against disease by filtering particles (cancer, pathogens) from the nymph |
| MALT | Mucosal-associated lymphoid tissue - lymphoid tissue found in mucous membrane |
| Lymph Nodes | Small pea-shaped patches of lymphatic tissue strategically located to filter the lymph as it flows through the lymphatic vessel. Tend to appear in clusters |
| Cervical Lymph Nodde | Drain and cleanse lymph coming form the head and neck areas. Enlarged tender cervical lymph noes often accompany upper respiratory infections |
| Axillary Lymph Nodes | Located in the axillary area (armpit). Drain and cleanse lymph coming from the upper extremities, shoulders, and breast area |
| Inguinal Lymph Node | Located in the groin region. Drain and cleanse lymph from the lower extremities an external genitalia |
| Lymph Nodules | Masses of lymphocytes and macrophages. Defensive cells that are concerned with immunity an phagocytosis; protect body from disease |
| Tonsils | Partially encapsulated lymph nodes in the throat area. Filter tissue fluid contaminated by pathogens that enter the body through the nose, mouth, or both. 3 sets |
| Palatine Tonsils | Small masses of lymphoid tissue located at the opening of the oral cavity into the pharynx. A tonsillectomy is most often performed on this particulate set of tonsils |
| Pharyngeal Tonsils | Adenoids. Located near the opening of the nasal cavity int he upper pharynx. Atrophy during adolescence |
| Lingual Tonsils | Back of the tongue. White spots |
| Thymus Gland | Locate int he mediastinum of the thoracic cavity. Plays a crucial role in the development of the immune system before birth and in the first few months after birth. Secretes thymosins |
| Thymosins | Promote the proliferation and maturation of special lymphocytes (T cells) in the lymphoid tissue throughout the body |
| Spleen | Largest lymphoid organ. Located in the LUQ of the abdominal cavity, just beneath the diaphragm. Stores blood. Destroys old RBCs. Filters blood and is composed of 2 types of tissue: white pulp and red pulp |
| White Pulp | Lymphoid tissue consisting primarily of lymphocytes surrounding the arteries |
| Red Pulp | Venous sinuses filled with blood and disease-preventing cells such as lymphocytes and macrophages. |
| Hypersplenism | Disorder in which an overactive spleen prematurely destroys red blood cells, white blood cells, and platelets, thereby causing anemia, leukopenia, and thrombocytopenia |
| Splenomegaly | An enlarged spleen, it usually accompanies hypersplenism an the excessive destruction of blood cells ) |
| Lymphadenopathy | Disease of the lymph noes, but is used synonymously with "swollen or enlarged lymph nodes" |
| Lymphedema | Condition in which there is localized tissue swelling cause by damaged lymphatic vessels and poor drainage of tissue fluid |
| Lymphoma | A solid malignant tumor of lymphoid cells, specifically the lymphocytes. Two main categories: Hodgkin Lymphoma (HL) and non-Hodgkin Lymphoma (NHL) |
