The Sickle cell disease is a genetically inherited deformed cell. These cells are deformed into crescent shaped moons. This is serious and can lead to blood clots. Since these cells are deformed, they usually can’t fit in the capillaries aka tubes that carry blood throughout your body. These sells can block the entrances to the capillaries and cause blood flow to stop being transferred from one area of the body to another.
