Leukocytes and Erythrocytes Comparison
Blood consists of an ample quantity of cells that fulfill different functions including oxygen transportation to the lungs and tissues, antibody formation, protecting body from infection and the other important missions. The life cycle of all cells has similar display, to a certain degree. However, the range of differences between cells remains more obvious. It can be obvious through the example of two kinds of cells: Red Blood Corpuscles (RBC) and White Blood Corpuscles (WBC), in other words - erythrocytes and leukocytes. As it comes clear from the names, the blood cells might be recognized due to their color identity. Being of a red bright color, red cells are considered as the most abundant ones in the blood. Erythrocytes account approximately 40-45 percent of blood volume (Blood Basics, 2010). Hemoglobin, being a component of RBC absorbs oxygen from the lungs and releases it in the tissues during the blood run. The mission of white cells, however, is to protect the body from infection. The quantity of WBC is much fewer, when comparing with an abundance of red cells. They account for about 1 percent only of our blood. White cells produce special defensive proteins, called antibodies, which recognize dangerous elements in the body. These two types of cells differ in their size and structure. Thus, a size of a red cell is approximately 6-8 μm and it has a shape of biconcave disc “with a flattened center…both faces of the disc have shallow bowl-like indentations” (Blood Basics, 2010). An average level of erythrocytes should make four to six million per cubic mm, depending on sex, height and weight of a human. The lack of nucleus helps the red cell easily change shape. On the other hand, its flexibility provides damages of the cell membranes during the travel through the smallest blood vessels, thus limiting red cell’s lifetime to four months only. Being...
