Which type of cells primarily compose granulocytes?

Granulocytes are a specific type of white blood cell characterized by the presence of granules in their cytoplasm, and they play a crucial role in the body's immune response. The correct choice identifies the primary types of granulocytes as neutrophils, basophils, and eosinophils.

Neutrophils are the most abundant type of granulocytes and are primarily involved in the early response to bacterial infection. They act quickly to engulf and destroy pathogens through a process called phagocytosis. Basophils are involved in allergic responses and inflammation, particularly releasing histamines and other chemicals that dilate blood vessels and draw other immune cells to the site of infection or injury. Eosinophils are particularly important in combating parasitic infections and are also implicated in allergic responses, especially those involving asthma and hay fever.

The other choices contain incorrect cell types for classifying granulocytes. Lymphocytes and monocytes are not granulocytes; they belong to different categories of white blood cells known as agranulocytes, which do not have granules in their cytoplasm. Monocytes are involved in the later stages of immune responses and can differentiate into macrophages and dendritic cells, while lymphocytes are primarily involved in adaptive immunity.
