Red blood cells in sickle cell disease are shaped like?

Explanation:
Red blood cells in sickle cell disease become sickle-shaped when oxygen levels drop. The abnormal hemoglobin S polymerizes inside the cell, pulling the cell into a rigid, elongated crescent form that looks sickle-shaped. This deformation under deoxygenation is the characteristic feature, distinguishing it from normal red cells, which are round and flexible (discoid). Descriptions like irregular lumps don’t fit the typical smooth, elongated outline of a sickled cell. While you’ll sometimes see crescent-shaped described, the essential idea is that the cells adopt a sickle-like morphology because of HbS polymerization in low oxygen.
