The correct Answer is:
To analyze the given statements regarding red blood cells (RBCs), we will evaluate each statement individually. ### Step-by-Step Solution: 1. **Evaluate Statement A**: - The statement claims that the average lifespan of RBCs in humans is about 120 days. - This statement is **true**. Research shows that red blood cells typically have a lifespan of approximately 120 days before they are removed from circulation. 2. **Evaluate Statement B**: - The statement claims that worn-out RBCs are destroyed only in the spleen, which is why it is referred to as the "graveyard of RBCs." - This statement is **false**. While the spleen does play a significant role in the destruction of old RBCs, it is not the only organ involved. The liver and bone marrow also contribute to the breakdown and recycling of red blood cells. 3. **Conclusion**: - Therefore, Statement A is true, and Statement B is false. ### Final Answer: - Statement A: True - Statement B: False
