Neutrophils, which make up 65% of the body's white blood cells are the most numerous. Because they are phagocytic they are mainly found at the sites of wounds where they begin to form what eventually becomes a scab by glueing themselves to the walls of blood vessels and engulf any bacteria that try to get into the body through the site of the wound.
Eosinophils make up anywhere from 2-4% of of the body's white blood cells and are mainly responsible for attacking parasites that enter the blood stream.
Basophils make up 0.5% of the body's white blood cells and are responsible for the production and secretion of antibodies.
Lymphocytes make up 20-25% of the body's white blood cells and are responsible for helping the body to develop immunity towards infections. Lymphocytes also produces antibodies, but unlike the Basophils these antibodies are designed specifically to target the excretions of harmful bacteria. They will also help the Neutrophils do their job by clustering the bacterium together so that they can be engulfed by the phagocytes easily.
Monocytes make up 3-8% of the body's white blood cells and are much like stronger, larger versions of the Neutrophils for they take on the bacteria that the Neutrophils are unable to handle. Monocytes are also phagocytic.
