acquired immunity

Question 1

Answer 4

adaptive

Question 5

What type of immunity do B cells provide?

Answer 5

Humoral immunity

Question 6

What do T cells primarily target?

Answer 6

Answer 7

C) Immediate response

Question 8

What is the role of antibodies in the acquired immune response?

Answer 8

Antibodies neutralize pathogens and mark them for destruction.

Question 9

True or False: The acquired immune response can remember previous infections.

Answer 9

True

Question 10

What are the two main types of T cells involved in the acquired immune response?

Answer 10

Helper T cells and Cytotoxic T cells

Question 11

Fill in the blank: The process by which B cells produce antibodies is called _____.

Answer 11

clonal selection

Question 12

What is the primary function of Helper T cells?

Answer 12

To activate B cells and other T cells.

Question 13

Multiple Choice: Which type of immunity is characterized by the presence of antibodies? A) Innate B) Acquired C) Passive D) Active

Answer 13

B) Acquired

Question 14

What is an antigen?

Answer 14

A substance that induces an immune response.

Question 15

True or False: The acquired immune response is the same for every pathogen.

Answer 15

False

Question 16

What is the significance of memory cells in the acquired immune response?

Answer 16

Memory cells allow for a faster and stronger response upon re-exposure to the same antigen.

Question 17

Fill in the blank: Vaccination is a method to induce _____ immunity.

Answer 17

active

Question 18

What is the main difference between active and passive immunity?

Answer 18

Active immunity involves the body generating its own response, while passive immunity involves receiving antibodies from another source.

Question 19

Multiple Choice: Which type of T cell kills infected cells? A) Helper T cells B) Cytotoxic T cells C) Memory T cells D) Suppressor T cells

Answer 19

B) Cytotoxic T cells

Question 20

What is the function of suppressor T cells?

Answer 20

To regulate and suppress the immune response to prevent overactivity.

Question 21

True or False: The acquired immune response can be enhanced by previous infections.

Answer 21

True

Question 22

What are cytokines?

Answer 22

Signaling molecules that mediate and regulate immunity and inflammation.

Question 23

Fill in the blank: The two main types of acquired immunity are _____ and _____ immunity.

Answer 23

humoral, cell-mediated

Question 24

What is the role of dendritic cells in the acquired immune response?

Answer 24

Dendritic cells capture and present antigens to T cells.

Question 25

Multiple Choice: Which of the following is an example of passive immunity? A) Vaccination B) Maternal antibodies C) Infection D) All of the above

Answer 25

B) Maternal antibodies

Question 26

What is the clonal expansion in the context of the acquired immune response?

Answer 26

The rapid multiplication of specific B or T cells upon encountering their specific antigen.

Question 27

True or False: Acquired immunity is present at birth.

Answer 27

False

Question 28

What is the significance of the primary and secondary immune responses?

Answer 28

The primary immune response is the initial response to an antigen, while the secondary immune response is faster and stronger due to memory cells.
