Study Notes
Sickle Cell Disease
- Hemoglobin S (HbS) replaces normal hemoglobin in the red blood cells of individuals with sickle cell disease.
Sickle Cell Characteristics
- Sickle cells can adhere to the endothelium, leading to obstruction of blood flow.
Red Blood Cell Lifespan
- The lifespan of sickled cells is shorter compared to normal red blood cells.
Sickle Cell Crisis
- Sickle cell crisis causes severe pain, damage to organs, and even death in individuals with sickle cell anemia.
Reversibility of Sickle Cells
- Sickle cells can resume a normal shape when rehydrated or reoxygenated.
