Question

Innate immunity is provided by

• A. Neutrophils
• B. T-cells
• C. B-cells
• D. Antibody

Answer 1

The Correct Option is A

Answer (a) Neutrophils

Answer 2

There are two forms of immunity:
1. Innate immunity is achieved by erecting various barriers against the entry of external agents or pathogens into our bodies. Because it is present at birth, it is also known as inborn immunity. This is a general defense; innate immunity is made up of four sorts of barriers.
2. Acquired immunity: acquired immunity is pathogen-specific and occurs after birth. When we first come into contact with a pathogen, our bodies start a response known as the initial response.

 

Answer 3

Innate immunity serves as the host's initial line of defense, preventing infection and attacking invading microorganisms. This nonspecific mechanism works quickly (minutes to hours), whereas the adaptive response takes days to weeks. Sweat, saliva, tears, skin, and lymphocytes offer innate immunity.
