Description:This photomicrograph of a blood smear revealed the presence of some of the normally-occurring cellular elements found throughout the body’s circulatory system. Included in this view were numbers of biconcave red blood cells (RBCs), or erythrocytes, and three types of white blood cells (WBCs), or leukocytes, a segmented eosinophil granulocyte (top) with its multilobular nucleus, a basophil granulocyte (bottom), and a small lymphocyte with its proportionally-large nucleus.
The RBCs are responsible for carrying out the transfer and delivery of oxygen and carbon dioxide at the cellular level, bringing oxygen to the cells of all the body’s tissues, and removing the waste product, carbon dioxide, from tissues. The WBCs eosinophil, basophil and lymphocyte are but three members of the body’s immune system responsible for protecting the body against allergens, pathogens such as viruses and bacteria, and participating in physiologic reactions ranging from mediation of the clotting process to lipid metabolism to name, but a few of many.
