Human bloods have differences precisely to the presence or absence of certain protein molecules called antigens and antibodies. The antigens can be found on the surface of red blood cells and the antibodies are in the blood plasma. Individuals have different types and combination of these molecules. Blood group is like a trait which we inherit to our parents. The blood group you belong depends on what you have inherited from your parents. There are three types of antigens: A antigen‚ B antigen

of but the transportation of oxygen and carbon dioxide by diffusion in human is insufficient‚ this distribution is enabled by a movement of fluid called blood‚ In effect human body use one molecule found in the red blood cell called haemoglobin‚ on the other hand the haemoglobin can be define as a molecule found in the red blood cell which deliver or transport oxygen to the rest of body muscles and tissues. In this our essay we are going to describe the chemical structure which form the

homeostasis about 2.5 million of those erythrocytes are destroyed and replace every second. The life cycle of an erythrocyte is 120 days. In the short lifetime the erythrocytes make an astonishing 75000 round trips between the lungs‚ heart and cells of the body. Erythrocytes do not possess a nucleus they are unable to repair or synthesize new cellular components and eventually they wear out. When they wear out most aging erythrocytes are pulled out of circulation by specialized leukocytes called

Beta Thalassemia Beta thalassemia is an inherited blood disorder characterized by the abnormal production of a blood protein called hemoglobin. This condition is caused by a mutation within the gene that is responsible for the healthy production of hemoglobin. In healthy people‚ hemoglobin carries oxygen to tissues and cells throughout the body. Patients with beta thalassemia do not have adequate levels of oxygen within the blood‚ which can cause anemia. There are two main types of beta thalassemia

by iron in the transport of oxygen. The structure of hemoglobin is a hemi group. A hemi group consists of an iron (Fe) ion held in a heterocyclic ring. Iron binds with oxygen. Therefore‚ it has a very important role in transporting oxygen in the blood. How is iron stored and transported in the body? Iron can be stored within intestinal entrecotes bound to ferritin and transported transversely along the basolateral membrane of intestinal entrecotes. The liver is the chief storage site for iron

" This occurs in biology in three main examples: 1. The clumping of cells such as bacteria or red blood cells in the presence of an antibody. The antibody or other molecule binds multiple particles and joins them‚ creating a large complex. 2. The coalescing of small particles that are suspended in a solution; these larger masses are then (usually) precipitated. 3. An allergic reaction type occurrence where cells become more compacted together to prevent foreign materials entering them

The “Pain” is inherited by an retriction blood flow through the body do to an abnormality in the cells. “Sickle Cell Anemia” a chronic illness discovered in 1910 by an American physician named James Bryan Herrick.

It is an illness that occurs when blood does not have enough healthy red blood cells or hemoglobin. Hemoglobin is an iron-rich protein that gives blood its red color (Geretsen). This protein helps red blood cells carry oxygen from the lungs to the rest of the body. Cells in the body do not get enough oxygen if hemoglobin
