The purpose of this lab is to correctly determine the blood type of four unknown synthetic blood samples through the use of three antibody serums; anti-A, anti-B and anti-Rh. By successfully determining the blood type of an individual, information such as the individual 's blood antigens and antibodies will be known and can help determine which blood types that individual can accept or donate. Blood, or whole blood, consists of about 55% plasma and 45% formed elements; which include platelets, white blood cells and red blood cells or erythrocytes (Martini et al., 2015). Plasma consists of 90% water and serves to transport minerals throughout the blood, especially clotting platelets to the site of an injury in order to prevent loss of blood (Martini et al., 2015).
Platelets and leukocytes are less than 0.1% of formed elements but nearly 99.9% are nuclei-lacking red blood cells, whose biconcave disk-shape increases surface area and allows for the diffusion of oxygen (Martini et al., 2015). Erythrocytes contain hemoglobin proteins, where each protein has four iron-containing heme groups that can bind one oxygen molecule each (Surgenor, 2013). In other words, each hemoglobin protein can carry four oxygen molecules and there are over 250 million hemoglobin proteins per cell.
Finally, white blood cells are crucial to the immune system to serve as a defense against invaders such as bacteria, viruses and parasites with the ability to recognize between “friend or…
