Immune System

Question 1

What are the two different types of resistance?

Answer 1

Non specific (innate) and specific (adaptive or learned)

Question 2

What are facts about Innate response?

Answer 2

It is present at birth
It helps protect against different substances (nonspecific)
No prior exposure to substance is necessary
It responds immediately
It includes a barriers of entry and molecular internal defenses

Question 3

What are examples of innate immune defenses?

Answer 3

Barriers to entry (skin and mucus membranes)
Protective proteins
Phagocytes and natural killer cells
Inflammatory response

Question 4

What are facts about adaptive response?

Answer 4

It takes days to be effective
There are two different types (CMI and Humoral)
It responses to specific antigens and involve T- and B-lymphocytes

Question 5

What are signs of the inflammatory response?

Answer 5

Redness (From increased blood flow)
Heat (From increased blood flow and increased metabolic activity)
Swelling (From increased fluid loss from capillaries)
Pain (From stimulation of pain receptors)

Question 6

What are the two types of protective proteins.

Answer 6

Complement (Involved in the inflammatory response/ poke holes in cells)
Interferons (send signals to warn neighboring healthy cells)

Question 7

What are the four main activities of plasma proteins?

Answer 7

Neutralization (makes pathogen less ineffective in establishing infection)
Agglutination (causes foreign cells to clump up)
Precipitation (forms a complex that becomes insoluble and precipitates out the body)
Opsonization (facilitates phagocytosis)

Question 8

What is pyrexia?

Answer 8

It is a fever that is caused by pyrogens
