• Leukocytes (WBCs) appear white when separated from blood. There are five different types of leukocytes, each of which has a different function.
o Granulocytes: The primary function of the granulocytes is phagocytosis, a process by which WBCs ingest or engulf any unwanted organism and then digest and kill it. The neutrophil is the most common type of granulocyte.
o Lymphocytes: The main function of lymphocytes is related to the immune response. Lymphocytes form the basis of the cellular and humoral immune responses.
o Monocytes: Monocytes are phagocytic cells. They can ingest small or large masses of matter, such as bacteria, dead cells, tissue debris, and old or defective RBCs.
• The primary function of thrombocytes, or platelets, is to initiate the clotting process by producing an initial platelet plug in the early phases of the clotting process.
• Hemostasis is a term used to describe the blood clotting process. This process is important in minimizing blood loss when various body structures are injured.
• Four components contribute to normal hemostasis: vascular response, platelet plug formation, the development of the fibrin clot on the platelet plug by plasma clotting factors, and the ultimate lysis of the clot.
• The spleen, which is located in the upper left quadrant of the abdomen, has four major functions: hematopoietic, filtration, immunologic, and storage.
• The lymph system—consisting of lymph fluid, lymphatic capillaries, ducts, and lymph nodes—carries fluid from the interstitial spaces to the blood.
