This document discusses the components of blood, including plasma, erythrocytes, leukocytes, granulocytes and agranulocytes, and thrombocytes. It defines each component, describes their properties, composition, functions, and production. Plasma is the liquid portion of blood that holds the cellular elements in suspension. Erythrocytes are red blood cells that transport oxygen. Leukocytes, or white blood cells, help fight infection. Granulocytes include neutrophils, eosinophils and basophils, while agranulocytes are lymphocytes and monocytes. Thrombocytes, also called platelets, are involved in blood clotting.
