Question

One the main differences between innate and adaptive defenses is that__________.

A) innate defense does not produce memory cells and adaptive defense produces memory cells

B) innate defense is triggered by antigens and adaptive defense responds to changes in the environment

C) innate defense is capable of generating memory cells and adaptive is not

D) innate defense produces antibodies and adaptive defense produces cytokines

Answer 1

CORRECT ANSWER IS OPTION A - innate defense does not produce memory cells and adaptive defense produces memory cells

REASON:

Innate immunity is the inborn immunity present in the body.

Examp,le for innate immmunity are Skin, lysozyme in the tear, Blood cells like Neutrophils, eosinophil, basophils,stomach acids,

This type of immunity act vey rapidly when it is exposed to the foriegn body.

It is Non specific immunity

Innate immunity is short lived , its action is only for a shorter period.

it doesnot produce any memory cell

Adaptive immunity is teh acquired immunity in the body .it is a slow acting immunity but the action is for more time.

It is mediated by Antibody production (Humeral immunity)

T lymphocyte mediated (Cell mediated immunity)

in an adaptive immunity when the B lymphocyte are exposed to the antigen , it bind with the B cell receptor(BCR) and activate the B lymphocyte .

Activated B lymphocyte produces plasma cell and MEMORY CELL

Plasma cell produce the antibody against the antigen

Memory cell will keep a memory of the infection and attack when the body is exposed to the same antigen .
