What is Sickle Cell Anemia?

Sickle Cell Anemia is when someones blood cells become a sickle shape and none-functional. Hemoglobin is the protein that is found in red blood cells. Hemoglobin carries the oxygen all over the body. Sickle Cell Anemia is caused by an abnormal hemoglobin. The Hemoglobin changes the shape of the cell into more of a crescent shape. Hemoglobin doesn't deliver enough oxygen to the rest of the body. They get stuck easier than blood vessels. Both of your parents have to have the abnormal hemoglobin. If you have one of the genes then you are a carrier


Malaria is a disease that is cause by parasites. The red blood cells are being destroyed. People who have the gene for Sickle Cell Anemia, one gene, are resistant to the disease.
