Introduction to Immunology Flashcards
1
Q
Immunology
A
the defense of the body against invading microbes
2
Q
3 Major Lines of Defense
A
Physical Barriers
Innate Immunity- rapid defenses
Adaptive Immunity- slow but highly effective and improves with time
3
Q
Cellular Innate Immunity
A
cellular mechanisms by which protective cells attack
invaders
4
Q
Humoral Innate Immunity
A
soluble molecules attack invaders
5
Q
Cell-Mediated Adaptive Immunity
A
intracellular invaders. Involves T lymphocytes- recognize antigen- proliferates helper T cell or CTL
6
Q
Humoral Adaptive Immunity
A
extracellular invaders. Involves B lymphocytes- proliferate- plasma cells produce immunoglobin
7
Q
Lysozyme
A
in human tears, kills gram-positive bacteria
8
Q
Examples of Physical Barriers
A
Cilia move mucous upward, coughing and sneezing, vomiting, urine flow
