Premium Sickle-cell disease Red blood cell Hemoglobin
Sickle-Cell Anemia is a genetic blood disorder caused by the presence of an abnormal form of hemoglobin. These hemoglobin molecules tend to aggregate after unloading oxygen forming long‚ rod-like structures that force the red cells to assume a sickle shape. Unlike normal red cells‚ which are usually smooth and malleable‚ the sickle red cells cannot squeeze through small blood vessels. When the sickle cells block small blood vessels‚ the organs are deprived of blood and oxygen. This leads to periodic

SCD is a serious disorder in which the body makes sickle-shaped red blood cells. “Sickle-shaped” means that the red blood cells are shaped like a crescent. Normal red blood cells are disc-shaped and look like doughnuts without holes in the center. They move easily through your blood vessels. Red blood cells contain an iron-rich protein called hemoglobin (HEE-muh-glow-bin). This protein
