In Hemolytic anemia, RBCs are destroyed?

After 120 days
Before their normal lifespan of 120 days
Without being destroyed
Only in the presence of an infection

The correct answer is: Before their normal lifespan of 120 days

In hemolytic anemia, red blood cells (RBCs) are destroyed before their normal lifespan of 120 days. Hemolytic anemia is characterized by the premature destruction of red blood cells, leading to a decrease in the overall number of circulating RBCs in the bloodstream. This destruction can occur due to various reasons such as autoimmune reactions, certain medications, inherited disorders, or exposure to toxins. The premature destruction of RBCs results in anemia, as the body cannot produce new red blood cells at a rate sufficient to compensate for the loss. Therefore, option B is the correct answer as it accurately describes the nature of RBC destruction in hemolytic anemia.
