Question

The term humor in humoral immunity implies
A. Hormones
B. Bone marrow
C. Plasma and lymph
D. Cerebrospinal fluid

Answer 1

Hint: Humoral immunity (also known as humoral immunity) is a type of immune response that is mediated by antibodies. The antibodies are produced in response to the entry of pathogens into the body.

Complete solution:
The Humoral immune system is a very vital part of the immune system as it protects the body against invading organisms and other foreign materials.
The Humoral part is done by the macromolecules, which may be antimicrobial peptides, antibodies, or complement proteins.
These macromolecules attack the pathogen (such as bacteria or other foreign substances), which have entered into the blood or other fluids.
Previously, these fluids (plasma and lymph) were called "humor".

So, the correct answer is option C.

Additional information:
Working of Humoral immune system -
When a bacteria (say) enters into the body, the B cells produce antibodies that attach to the invader so that they can target and destroy it.
B cells take the help of helper T cells to produce a certain type of antibody, which is tailor-made for that particular invader.
Humoral immunity is different from cell-mediated immunity as the latter involves the activation of phagocytes, T-lymphocytes, and the release of cytokines in response to an antigen (or antibody generator).

Note: The ability of the immune system of the body to defend against disease and infection is known as immunity. The adaptive immune system provides two types of immunity (humoral and cell-mediated immunity) and they are dependent on the function of B and T cells.
