Basophils

Basophils are white blood cells that store the chemicals heparin and histamine and are used to promote inflammation (example: allergies). Basophils are distinguished by their s-shaped nucleus and large granules.

Leukocytes

Leukocytes are the general term for "white blood cells". These are the immune system/defense cells of the body. There are five major types of leukocytes in the body: neutrophils, eosinophils, basophils, monocytes, lymphocytes.

Lymphocytes

There are two types of lymphocytes, T & B cells: lymphocytes are responsible for carrying out specific immune responses and primarily attack cells (for example, attacking cancerous and virus-infected cells).

Monocytes

Monocytes are the largest leukocytes. They are circulating phagocytes When debris, microbes or parasites invade the tissues, monocytes attempt to engulf and devour the invaders. Monocytes are classified by their large, horseshoe-shaped nucleus.

Neutorphils
