Week 3

Question 1

Name three functions of the immune system:

Answer 1

1. protection against infectious disease
2. destruction of malignant transformations (cancer)
3. promotion of tissue repair

Question 2

Can you name two unwanted side efffects of immune responses?

Answer 2

1. discomfort and sickness
2. tissue damage

Question 3

Explain how tissue damage can be caused by the immune system.

Answer 3

the immune system is basicly an army that attacks the pathogen (infection for example). But often it also attacks surrounding cells and this can create collateral damage such as pain or tissue damage for example.

Question 4

give two synonyms for immune cells

Answer 4

1. white blood cells
2. leukocytes

Question 5

immune cells are produced by which cells? in which area?

Answer 5

stem cells, bone marrow

Question 6

immune cells are divided in to which two groups of cells?

Answer 6

Question 7

lymphoid lineages are devided in to what?

Answer 7

Question 8

myeloid lineage are diveded in to which four cells?

Answer 8

Question 9

name the most prominant function of granulocytes

Answer 9

Destroy pathogens such as bacteria, viruses, and fungi.

Question 10

name the most prominant function of monocyte/macrophage

Answer 10

They play a critical role in clearing infections and aiding in the cleanup and repair of tissues.

Question 11

name the most prominant function of mast cells

Answer 11

Mast cells play a central role in allergic reactions.

Question 12

Name the most prominant function of NK cells

Answer 12

kill of canceres cells

Question 13

Name the most prominant function of T cells

Question 14

Name the most prominant function B cells

Question 15

What are the front lines of effection?

Answer 15

skin or mucosa (tissue in your mouth or nose)

Question 16

from the frontlines the infection goes to the headquaters. Which is?

Answer 16

the lymph nodes

Question 17

describe the immune response cycle. implementing the following terms:
* sentinel cells (explain)
* lymph nodes
* lymphocytes (explain
* lymphatic (explain)

Answer 17

1. sentinel cells grab infectious agents (microbes)
2. lymphocytes cells that live in lymph nodes and become active (meaning of effector)
3. lymphatic system (fluid transport system parralal to bloodvessels)

Question 18

if an agents breaches the frontline, which three barriers do we have?

Answer 18

1. phyical (body temperature)
2. chemical (antimicorobial protein antibodies)
3. phagocytic cell response=wraps around agent (what the sentinel cells do)
