What is leucosyt and its types?

Leukocytes, commonly known as white blood cells, are a crucial component of the immune system, helping the body fight infections and other diseases. There are several types of leukocytes, which include neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each type has a specific role; for example, neutrophils are primarily involved in responding to bacterial infections, while lymphocytes are essential for adaptive immunity. The balance and function of these cells are vital for maintaining health and responding to pathogens.
