What is the compared shape of a red blood cell to that of a sickle cell?

Answer 1

The red blood cells have a sickle shape, hence the name. They receive this shape from a protein in normal blood cells that is mutated. They carry less blood and block veins and capillaries easily.

Answer 2

Sickle cell anemia is a serious disease in which the body makes sickle-shaped red blood cells. "Sickle-shaped" means that the red blood cells are shaped like a "C." 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 the protein hemoglobin. This iron-rich protein gives blood its red color and carries oxygen from the lungs to the rest of the body. Sickle cells contain abnormal hemoglobin that causes the cells to have a sickle shape. Sickle-shaped cells don't move easily through your blood vessels. They're stiff and sticky and tend to form clumps and get stuck in the blood vessels. The clumps of sickle cells block blood flow in the blood vessels that lead to the limbs and organs. Blocked blood vessels can cause pain, serious infections, and organ damage.

Answer 3

They come in the shape of a sickle used in harvesting crops or the shape of a crescent moon or the letter "C".
