Eosinophils are a type of white blood cell, part of the body’s immune system. They help the body identify and fight infection, but they can also be present in diseases such as asthma, allergies, and parasitic infections.

A) They Produce the Coating of a Pathogen by Complement

This statement is true. Eosinophils play an important role in complement-mediated immunity, a form of the body’s defense against foreign invaders. Complement is a group of proteins that circulate in the bloodstream and are activated when the body detects a foreign substance. Eosinophils produce the coating of a pathogen by complement, which helps to contain and contain the foreign pathogen.

B) They Are Intact Skin, Sebum, Tears, Etc.

This statement is false. While eosinophils are found in the blood, they are not found in intact skin, sebum, tears, or other bodily fluids.

C) They Release Prostaglandins and Leukotrienes in Response to an Infection

This statement is true. Eosinophils release prostaglandins and leukotrienes in response to an infection. These chemicals help the body combat the infection by killing the pathogen and promoting inflammation, which helps to contain and clear the infection.

Eosinophils have a variety of important roles in the body, from helping to identify and fight infection to contributing to allergic and inflammatory diseases. They produce the coating of a pathogen by complement and release prostaglandins and leukotrienes as a response to an infection, helping the body protect itself against foreign invaders.
