Immune Cells & Tissues: Part Two Flashcards
1
Q
what do primary immune organs do
A
organs where immune cells develop, mature, and become immunocompetent
2
Q
what are the primary immune organs
A
- bone marrow
- thymus gland
3
Q
what do the secondary immune organs do
A
organs/tissues where mature and trained cells mount an adaptive immune response
4
Q
what are the secondary immune organs
A
- spleen
- lymph nodes
- tonsils
- adenoids
- appendix
- Mucosa Associated Lymphoid Tissues (MALTs)
5
Q
thymus gland
A
- where T cells mature and become immunocompetent
- bilobed structure
- located in thoracic cavity in front of the heart
- largest and most active in pre-adolescents
6
Q
lymph nodes
A
- connected to the lymphatic system
- site where immune responses are mounted to antigens present in the lymph/tissue
- act as filters
7
Q
spleen
A
traps blood borne pathogens
8
Q
lymphatic system
A
- lymphoid organs are connected to each other and to tissues via blood and lymph
- excess fluid is picked up by lymphatic vessels and drained into the blood
9
Q
Mucosal Associated Lymphatic Tissues (MALTs)
A
- associated with the mucosa of the lungs, GI tract, and urogenital tract
- less organized than the lymph nodes and spleen
