What is the most important function of leukocytes?

The leukocyte, commonly known as a white blood cell (or WBC), is a major component of the body’s defenses against disease. Leukocytes protect the body against invading microorganisms and body cells with mutated DNA, and they clean up debris.

What are the five leukocytes and their functions?

The five main types of blood cells are basophils, neutrophils, eosinophils, monocytes, and lymphocytes. Basophils are the cells mainly responsible for allergic reactions. They defend against parasites and bacteria by excreting two chemicals: heparin and histamine. Heparin is a blood-thinning substance.
