Adaptive Immunity Flashcards
Against specific pathogens or changed body cells
Adaptive immunity
Defense cells in the blood B lymphocytes
Adaptive
Antibodies
Adaptive immunity
Defense cells in the tissue - T lymphocytes
Adaptive
Components of the adaptive immune system
Cellular - t lymphocytes, b lymphocytes, plasma cells
Humoral- antibodies, cytokines
Key cells involved in the adaptive immune response
Lymphocytes
Allow body to recognize , remember and response to a specific stimulus an antigen.
Adaptive immunity
Can result in the elimination of
And recovery from disease and the host often acquires a specific immunologic memory
Adaptive immunity
Allow the host to respond more effectively if reinfection with the same microorganism occurs.
Adaptive Immunity
Direct cell to cell contact
T lymphocytes
Antibody production
B lymphocytes
20-40% WBC
Lymphocytes
7 - 10 mm in diameter and has large rounded nucleus that may be somewhat indented. ‘
Lymphocytes
Primary-lymphoid organs
Bone marrow
thymus
Secondary lymphocytes organs
Spleen, lymph nodes, appendix, tonsils
Activation site-antigen
Secondary organs ( lymphocyte)
Are small similar sites when the ABC
Lymphocytes
Provide undifferentiated progenitor cells
Bone marrow
Maturation site of lymphocyte
Primary lymphoid organ
Where B cells/ B lymphocyte matured
Bone marrow
Can be considered the largest tissue of the body with a total weight of 1300 - 1500 g in the adult
Bone marrow
Functions as the center for antigen independent lymphopoiesis
Bone marrow
Main source of hematopoietic stem cell B cell produced and body.
Bone marrow
Maturation site of T cells
Thymus
Small, flat, bilobed organ found in the thorax
Thymus
It weighs an average of 30 o at birth teaches 35 puberty and then gradually atrophies
Thymus
97% of the cortical cells die in the - before becoming mature Tcells.
Thymus
Stimulates T cell maturation
- Endocrine gland
Thymocytes(inmaturet cells)
Cortex
Mature T cells
Medulla
