Question 1

Match the appropriate characteristic with the type of immunity.
-B cells
A)Innate immunity
B)Antibody-mediated immunity
C)Cell-mediated immunity
D)Both antibody-mediated and cell-mediated immunity
E)Innate immunity, antibody-mediated immunity, and cell-mediated immunity

Accepted Answer

B cells are primarily involved in antibody-mediated immunity as they produce and secrete antibodies that target and neutralize pathogens.

Answer: D 
 While B cells are primarily involved in antibody-mediated immunity, they also play a role in cell-mediated immunity through their ability to present antigens to T cells and activate them. Therefore, B cells are involved in both antibody-mediated and cell-mediated immunity.

Accepted Answer

All types of immunity have their origins in cells that are initially produced in the red bone marrow. Innate immunity cells, such as natural killer cells and phagocytes, antibody-producing cells (B cells) for antibody-mediated immunity, and T cells for cell-mediated immunity, all originate from stem cells in the bone marrow.

-Protection against intracellular antigens
A)Innate immunity
B)Antibody-mediated immunity
C)Cell-mediated immunity
D)Both antibody-mediated and cell-mediated immunity

Accepted Answer

Cell-mediated immunity, primarily involving T cells, is specifically designed to target and destroy intracellular pathogens, such as viruses and some bacteria, that reside within host cells.

Question 10

Match the appropriate characteristic with the type of immunity.
-Histamine produced
A)Innate immunity
B)Antibody-mediated immunity
C)Cell-mediated immunity
D)Both antibody-mediated and cell-mediated immunity
E)Innate immunity, antibody-mediated immunity, and cell-mediated immunity

Accepted Answer

Histamine is produced as part of the innate immune response, which is the body's first line of defense against pathogens. It is released by mast cells and basophils during inflammatory responses.

Question 11

Match the appropriate characteristic with the type of immunity.
-Provide protection against extracellular antigens
A)Innate immunity
B)Antibody-mediated immunity
C)Cell-mediated immunity
D)Both antibody-mediated and cell-mediated immunity
E)Innate immunity, antibody-mediated immunity, and cell-mediated immunity

Accepted Answer

Antibody-mediated immunity (also known as humoral immunity) is specifically designed to target and protect against extracellular pathogens and antigens through the production of antibodies by B cells.

Question 12

Match the cell of adaptive immunity with its function.
-B cell
A)Quick and responsive to antigen, remembers previous exposure
B)After activation, differentiates to become plasma cell or memory B cell
C)Produces antibodies
D)Destroys cells by lysis or by production of cytokines
E)Activates B and effector T cells

Accepted Answer

B cells, after activation, differentiate into plasma cells that produce antibodies or memory B cells that remember the antigen for quicker response upon re-exposure.

Question 13

Match the appropriate characteristic with the type of immunity.
-Cells mature in thymus gland
A)Innate immunity
B)Antibody-mediated immunity
C)Cell-mediated immunity
D)Both antibody-mediated and cell-mediated immunity
E)Innate immunity, antibody-mediated immunity, and cell-mediated immunity

Accepted Answer

Cells maturing in the thymus gland is a characteristic of T cells, which are a crucial part of cell-mediated immunity. This process does not directly relate to innate immunity or antibody-mediated immunity (which involves B cells).

Question 14

Match the type of cell with its function.
-Neutrophil
A)First cell to enter infected tissue
B)Will become macrophage in tissue
C)Lyses tumor and virus-infected cells
