Question

The main function of neutrophils is to do which of the following?

1) Release chemical substances to kill cells
2) Remembering the chemical structure of the foreign material.
3) Engulf and digest foreign materials
4) Produce antibodies in response to foreign material

Answer 1

Neutrophils primarily function to engulf and digest foreign materials, acting as an early line of defense in the immune system by phagocytizing pathogens and using chemicals to destroy them.

Step-by-step explanation:

The main function of neutrophils is to engulf and digest foreign materials. These phagocytic cells are integral to the body's immune response, and they represent one of the first lines of defense against microbial invaders. Neutrophils are known to phagocytize pathogens that infiltrate the body, thus preventing them from proliferating or producing toxic substances that may harm cellular structures. Once a pathogen has been engulfed, neutrophils use chemicals like histamines and cytokines to break down and eliminate the pathogen from the body.
