This lack of oxygen can cause pain and deepen in the arms, legs and organs (eg. Spleen, kidneys, brain). Sickle cell anemia is named aft(prenominal) the change of shape (sickling) of red blood cells. The sickling is caused by an anomalous tone of hemoglobin (a comp wiznt of transferrin present in red blood cells that carries oxygen) called hemoglobin S.

This is a trait. In general, these people have n! o symptoms, just perhaps when they are at a high altitude, for theoretical account when flying unpressurized airplane. There is less oxygen available at high altitudes and, therefore, the red blood cells may become more than fragile and deformed, thus increasing their dip to take a sickle and to destruction (hemolysis). In areas where malaria is present, it was spy that people with sickle cell trait were...If you want to get a full(a) essay, order it on our website: BestEssayCheap.com
