Sickle Cell Anaemia :: Free Essays

reap hook Cell Anaemia The disorder affects the carmine tune cells, which accept a special protein called hemoglobin . The function of haemoglobin is to carry group O from the lungs to all parts of the body. People with Sickle Cell Anaemia charter Sickle haemoglobin which is different from the normal haemoglobin. When sickle haemoglobin gives up its group O to the tissues, it sticks together to form long rods inside the red blood cells making these cells rigid and sickle-shaped. Normal red blood cells preserve twine and flex easily.Blocked blood vessels Because of their shape, sickled red blood cells cant squeeze through minuscule blood vessels as easily as the almost donut-shaped normal cells. This can lead-in to these small blood vessels getting blocked that then lolly the oxygen from getting through to where it is needed. This in turn can lead to horrific pain and damage to organs. Every single has two copies of the gene for haemoglobin on e from their mother and one from their father. If one of these genes carries the instructions to make sickle haemoglobin (HbS) and the other carries the instructions to make normal haemoglobin (HbA) then the individual has Sickle Cell Trait and is a carrier of the sickle haemoglobin gene. This means that this person has enough normal haemoglobin in their red blood cells to keep the cells flexible and they dont produce the symptoms of the sickle cell disorders. They do however have to be careful when doing things where there is less oxygen than normal such as scuba diving, activities at high stature and under general anaesthetics. If both copies of the haemoglobin gene carry instructions to make sickle haemoglobin then this will be the besides type of haemoglobin they can make and sickled cells can occur. These people have Sickle Cell Anaemia and can suffer from anaemia and severe pain. These severe attacks are known as Crises. Over time Sickle Cell sufferers can experience damage to organs such as liver, kidney, lungs, heart and spleen. Death can be a result.
