Answer:

Explanation:
The blood contains five different types of white blood cells namely the monocytes, neutrophils, basophils, eosinophil and lymphocytes.
These white blood cells perform different functions in the human body as.
1. The monocytes are the cell with a nucleus which becomes phagocytic when it recognises a pathogen and the cell thus is known as the macrophage.
2. The neutrophils are the WBC which are found in abundant amount in cells and activate the T-lymphocytes and kill the bacteria cell.
3. The eosinophil is the cells with lysosomes which helps in killing the larger pathogen in the human body like the larger insects.
