Detailed explanation-1: -T and B lymphocytes are the two main types. Macrophages are large white blood cells that reside in tissues that specialize in engulfing and digesting cellular debris, pathogens and other foreign substances in the body.

Detailed explanation-2: -Leukocytes are part of the body’s immune system. They help the body fight infection and other diseases. Types of leukocytes are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).

Detailed explanation-3: -Two types of lymphocytes comprise the adaptive immune system-B cells and T cells. B cells mature in the bone marrow (hence the name “B cell”). Cells that eventually become T cells travel from the bone marrow to the thymus by way of our bloodstream where they mature (hence the name “T cell”).

Detailed explanation-4: -A type of immune cell that can surround and kill microorganisms, ingest foreign material, and remove dead cells. It can also boost immune responses. Monocytes, macrophages, and neutrophils are phagocytes.

Detailed explanation-5: -White blood cell formation occurs in the soft tissue inside of your bones (bone marrow). Two types of white blood cells (lymphocytes) grow in the thymus gland (T cells) and lymph nodes and spleen (B cells).
