1 Transports O2, CO2, nutrients, hormones, heat and wastes. 2  Regulates pH, temperature, water content of cells. 3  Protects against blood loss through clotting. 4  Protects against disease through phagocytic white blood cells and antibodies. 5  The process by which blood is made is called Haemopoiesis.
What is the purpose of white blood cells? White blood cells (WBC), sometimes re-ferred to as leukocytes, are produced by the immune system to help defend the body against infection. They are formed in the bone marrow and enter the blood for migration to key organs; such as the spleen or lymph nodes. These cells are bigger than red blood cells, and there are far fewer WBCs in the bloodstream. A high white blood cell count likely in-dicates that an infection is present somewhere in the body, whereas a low number might indicate that an infec-tion or disease has slowed the ability of the bone marrow to produce new white blood cells. Typically one cubic millimeter of blood contains about 10,000 white blood cells. There are several different types of white blood cells, which are identified in a CBC with differential blood test. What is the purpose of red blood cells? Red blood cells (RBC), often referred to as erythrocytes, are responsible for de-livering oxygen throughout the body. There are between 3.6 to 6.1 million in
