When discussing the functiоn оf blоod, аn immediаte response seems to be its trаnsport of oxygen, but other important functions of the blood include transport of carbon dioxide, fighting infection, and coagulation.The white blood cells (leukocytes), those without the ability of carrying the pigmented chemical hemoglobin, are responsible for fighting infection. They differ from red blood cells in that they are usually larger, have a nucleus, and without staining appear white in color. Leukocytes can be divided into two groups, granulocytes and agranulocytes. Granulocytes can be found in three forms: neutrophils, eosinophils and basophils. The difference between these cells becomes apparent when cells are stained.Neutrophils have a multi-lobed nucleus and are the first WBC on the site of an infection. They have the ability to phagocytize a foreign particle or microbe. Eosinophils have a bilobed nucleus and their granules take up the eosin stain and become red in color. Not much is known about the function of eosinophils, but they are known to increase in numbers when there is a parasitic worm infection and in some allergies. A basophil's nucleus is almost totally obscured by the cytoplasmic granules within the cell. These granules take up the basic stain and become colored dark bluish purple. Basophils have the ability to enter tissues and release their histamine containing granules.There are two types of agranulocytes: monocytes and lymphocytes. Monocytes are the largest of the leukocytes with a kidney-shaped nucleus. They have phagocytic capabilities and can be found either in the blood or permanently stationed in tissue (such as the alveoli of the lungs) and are then called macrophages. Lymphocytes are the second type of agranulocytes and contain a large round nucleus that just about takes up the entire cell; very little cytoplasm is noticeable when observing these cells. These cells have one of two functions: production of antibodies or cell mediated immunity.Coagulation of the blood is dependent on the action of platelets (thrombocytes) within the blood and chemical components called factors (calcium ions, enzymes, and molecules associated with damaged tissues) within the blood. The platelets first form a plug at the site of the blood vessel injury. The actual clot is formed by a complex action in which coagulation factors activate each other in a cascade manner. This cascade eventually forms fibrin strands that trap erythrocytes at the site of the vessel injury and thus form a clot.We will now learn to identify the formed elements of blood.
