Question 1

What are the Antimicrobial proteins found as the Nonspecific Interior Barriers?

Answer 1

Interferons + Complement Proteins

Question 2

Interferons are a category of

Answer 2

Cytokines

Question 3

What are Cytokines?

Answer 3

Small proteins made by the body

Question 4

What is the function of cytokines?

Answer 4

They regulate, facilitate, and help our immune system

Question 5

How do Cytokines help our immune system?

Answer 5

• Communicate between cells like cell to cell signaling
• Control development and behavior of immune cells
• Play a role in inflammatory response

Question 6

How do interferons play a role in our body’s response to an infection?

Answer 6

They stimulate natural killer cells to destroy virus-infected cells

Question 7

What triggers the cell to produce interferons?

Answer 7

The entering of a virus

Question 8

Interferons are released into the cell via

Answer 8

Exocytosis

Question 9

How do interferons act in order to respond to an infection?

Answer 9

They function like hormones and locate receptors to bind to

Question 10

What happens after an interferon binds to a receptor?

Answer 10

The neighboring cell then produces anti-body proteins to protect itself from virus

Question 11

What is the function of complement proteins?

Answer 11

• They increase the likelihood of cells to be phagocytized
• Play a role in the inflammatory response
• Increase likelihood of lysis (burst)

Question 12

How do complement proteins increase the likelihood of cells to be phagocytized?

Answer 12

They mark cells for destruction

Question 13

Inflammation is a type of physiological response which

Answer 13

Causes redness, heat, swelling, and pain

Question 14

Within inflammation, what causes for changes in blood vessels?

Answer 14

Chemicals released like histamine and cytokines to get body tissue to react

Question 15

What happens to the arterioles in inflammation?

Answer 15

They will vasodilate, allowing for an increase in blood flow

Question 16

The vasodilation of arterioles causes for resistance to

Answer 16

Decrease

Question 17

What happens in capillaries during inflammation?

Answer 17

There is an increase in permeability and they get leaky

Question 18

What happens when the capillaries experience an increase in permeability?

Answer 18

White blood cells leave the capillaries and go out to phagocytize any debris

Question 19

Chemotaxis is the

Answer 19

Recruitment of leukocytes

Question 20

Fevers come in response to

Answer 20

Different pathogens

Question 21

During a fever, what does the body do?

Answer 21

Reset the set point

Question 22

What do the immune cells do during a fever?

Answer 22

They secrete pyrogens

Question 23

What is the function of pyrogens?

Answer 23

They talk to hypothalamus, which regulates body temperature

Question 24

What happens in the onset stage of a fever?

Answer 24

There are chills

Question 25

During the stadium stage, the fever is

Answer 25

Maintained

Question 26

Defervescence is when the

Answer 26

Set point is reset

Question 27

The Adaptive Immune system is known as

Answer 27

Acquired immunity

Question 28

The Adaptive Immune system is systemic, meaning its response is

Answer 28

Not restricted to the site of injury

Question 29

The Humoral Adaptive system is

Answer 29

Antibody mediated

Question 30

The Humoral Adaptive system is driven by

Answer 30

B Cells

Question 31

The Cell-Mediated Adaptive system is

Answer 31

Cellular

Question 32

The Cell-mediated Adaptive system is driven by

Answer 32

T Cells
