![]() This results in blockage and a lack of oxygen reaching parts of the body causing pain or damage to vital organs. Their blood cells are sickle shaped and rigid and therefore cannot pass through small blood vessels. Those with sickle cell anaemia have a different type of haemoglobin, HbS. Most people have normal haemoglobin or HbA their blood cells are doughnut shaped and flexible, allowing them to pass easily through even the smallest vessels. Within the blood vessels are red blood cells, which contain a protein called haemoglobin whose function is to carry oxygen from the lungs to all parts of the body. A secondary aim is to make contribution to medicine by analyzing particular abnormal or diseased states in the hope of improving diagnosis or treatment (Pedley, 1980). Young summarized the essence of this desire as understanding the physical events that take place in normal animal and thereby make contribution to physiology. The desire to quantitatively understand both the microscopic and macroscopic behaviour of blood when it flows through the vessels has supplied the motivation for appropriate investigations. The higher the viscosity the more like the crisis will occur.Įmmanuel O. ![]() We deduced that increase viscosity which all sickle cell patient are prone to leads to reduced flow and hampers the distribution of oxygen to essential areas of the body. The present study used a one-dimension model of flow in the arteries to investigate the effect of increase viscosity on small pressure disturbance and on the arterial compliance and the sequence of shock. People with the HbS type of red blood cell have their cell sickle. Many factors affect the flow of blood in the arteries and other small vessels among which are the diameters of the various vessels, the viscosity of the blood and various constituents of the blood.
