what components make up white blood cells
Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: 1  transporting oxygen and nutrients to the lungs and tissues.2  forming blood clots to prevent excess blood loss.3  carrying cells and antibodies that fight infection.hite blood cells protect the body from infection. They are much fewer in number than red blood cells, accounting for about 1 percent of your blood. The most common type of white blood cell is the neutrophil, which is the immediate response cell and accounts for 55 to 70 percent of the total white blood cell count.
