Q. Consider the following Statements:
- Spleen is also known as the ‘graveyard of RBCs’.
- The lifespan of RBCs is 90 days.
Which of the Statement(s) given above is/are correct?
Answer:
Only 1
Notes:
- The first statement is correct. The spleen is indeed often referred to as the 'graveyard of RBCs' (red blood cells) because it is one of the sites in the body where old, damaged, or senescent red blood cells are broken down and recycled.
- The second statement is not correct. The typical lifespan of red blood cells (RBCs) is about 120 days, not 90 days. After this period, they are usually removed from circulation by the spleen.
