Blood Leukocytes Leukocytes protect the body against microorganisms and remove dead cells and debris. Granulocytes contain cytoplasmic granules: and there are three types of granulocytes: neutrophils are small phagocytic cells, eosinophils reduce inflammation, and basophils promote inflammation. Agranulocytes have two types of very small granules: lymphocytes are involved in antibody production and other immune system responses; monocytes become macrophages that ingest microorganisms and cellular debris.

Unformatted text preview: flow. Platelet Plugs o Minor damage to blood vessels is repaired by platelet plugs. o Platelets use integrins to adhere to collagen, release chemicals (ADP and thromboxanes) that activate other platelets, and connect to one another with fibrinogen to form platelet plugs. Blood Clotting o Blood clotting, or coagulation, is formation of a clot (a network of protein fibers called fibrin). o There are three steps in the clotting process: Activation of clotting factors by connective tissue and chemicals, resulting in the formation of prothrombinase. Conversion of prothrombin to thrombin by prothrombinase. Conversion of fibrinogen to fibrin by thrombin....
