WebIn SCD, a chemical change in hemoglobin causes the formation of long rods. These rigid rods change the shape of the red blood cell into a sickle (which looks like a crescent). The sickle-shaped cells do not pass easily through blood vessels. They can clog or break apart which also leads to decreased red blood cell life.
