UNIT 4 7C: The lymphatic system Flashcards
Lymphocyte
A type of white blood cell; includes B and T cells
Adaptive immune response
Response of the vertebrate immune system to a specific antigen, which typically results in immunological memory
Interstitial Fluid
Fluid that collects in spaces between cells and tissues
Lymph
Colourless fluid that flows through the lymphatic system
lymphoid Organ
Organ involved in the production or function of lymphocytes
What do the primary lymph organs include
The bone marrow
The thymus
What cells originate from bone marrow
B and T lymphocytes
Example of a secondary lymphoid organ
Lymph nodes, spleen tonsils
What are the key structures of the lymphatic system
- Lymphatic capillaries
- Lymphatic vessels
- Lymph node
Lymphatic capillaries
Closed-ended tubes where interstitial fluid that is bathing the tissue enters through mini-valves of the capillary
Lymphatic vessels
bring lymph to the lymph node and return lymph to the blood through a lymphatic duct into the vein located near the clavicle
Lymph Node
A major site of filtration for the identification of non-self antigens to trigger the adaptive immune response
