RBCs give blood its characteristic red color”.
Hemoglobin is a metalloprotein, which means it is a protein that includes iron as one of its constituent atoms. For the reason of oxygen distribution, hemoglobin has multiple chemical “slots” for storing oxygen. This oxygen is acquired from the heart, where red blood cells are replenished with oxygen from the lungs. According toToole(2004: 32) “Red blood cells are unusual in having no nucleus, mitochondria and they are much thinner in the middle and so form a biconcave shape”.
The red blood cell is the main component of the circulatory system, also known by the name of cardiovascular system. In the circulatory system, the channels know as arteries hold oxygen-rich blood for distribution to the body, while veins give
back oxygen-poor blood to the heart for replenishment. The oxygen levels of blood can be assessed by looking at its color – oxygen-poor blood has bluish color, while oxygen-rich blood looks red. The second important function to carrying oxygen although less commonly known, is the capability of red blood cells to carry carbon dioxide. CO2 is a waste product formed due to metabolism in every cell in the human body
Red blood cells measure a diameter of about 6-8 micrometers (millionths of a meter), similar in size to much of the cells in the body. An RBC is biconcave in shape.Rosenberge (2010)states that “Red blood cells completely lack in most other common cellular parts, such as a nucleus with DNA, or mitochondria”. Due to their small shape and physical structure, the RBC can squish in to the small capillaries where the blood vessels are the smallest. Without this nature of flexibility , they have a high chance of getting stuck and cause obstructions in the circulation Because red blood cells are so important to your body, when they dont work properly, it often leads to
