Given below are two statements.

Statement I: Eosinophils are granulocytes which comprise 2-3 per cent of total WBCs. 

Statement II: Eosinophils migrate to sites of parasitic invasions and allergic responses. 

In light of given statements, choose the correct answer from the options given below.

Statement I is true. Eosinophils are a subtype of white blood cells (WBCs) known as granulocytes. They are called "granulocytes" because their cytoplasm contains granules that are visible under a microscope. Eosinophils typically comprising about 2-3 percent of the total white blood cell population in a typical blood sample.

Statement II is true. Eosinophils play a significant role in allergic reactions. They combat the effects of histamine, which is released during allergic responses and can cause symptoms like itching, swelling, and inflammation.
Eosinophils also have a phagocytic function, meaning they can engulf and digest antigen-antibody complexes, helping to remove foreign substances from the body. Another essential function of eosinophils is their ability to combat parasitic worms (helminths). Eosinophils are effective in attacking and destroying these parasites, contributing to the body's defense against parasitic infections.
