Red blood cells are responsible for transporting oxygen in the blood. People with sickle cell anemia were born with a defective gene that results in sickle-shaped red blood cells. Individuals with the disease often suffer pain in their extremities due to the build-up of these cells causing blockages in the blood vessels. The shape of the blood cells also reduces the amount of oxygen transported in the blood.

The image below shows a side-by-side comparison of normal and sickle-shaped red blood cells.
