Test your knowledge on Hereditary Hemolytic Anemia - round, a condition caused by either a defect in red cell structure or external factors that reduce the lifespan of red blood cells. Learn about specific abnormalities such as Hereditary spherocytosis, which alters the shape of red blood cells and makes them more vulnerable to damage. Discover the impact of these abnormalities on red blood cell survival.
