The Immune System Flashcards
1
Q
Innate
A
- Born with it
- Fast nonspecific response to non-self
- Physical barriers, chemicals, white blood cells
- At location
2
Q
Adaptive
A
- Slow response developed after encountering a specific pathogen
- B-cells, T-cells, antibodies
- Away from infection
3
Q
Complement
A
Hybrid of adaptive and innate immune system
4
Q
Physical Barriers
A
Skin
Mucosa (Respiratory, GI, Urinary)
5
Q
Chemical Barriers
A
- Stomach acid (HCl)
- Lysozyme in sweat and tears
6
Q
Cell
A
- Macrophages: activate innate system
- Dendritic cells: activate specific systems
7
Q
What happens when a pathogen breaks through physical or chemical barriers?
A
- Macrophages: recognize pathogen and activate innate response
• Phagocytosis
•Cytokine release (sounds the alarm)—> inflammation
