Current Question (ID: 14589)

Question:

Which of the following are not correct: (i) Spleen is the graveyard for RBC (ii) All the mammals have biconcave RBCs (iii) Clotting factors present in plasma are in active form. (iv) All the substances released by platelets are involved in clotting only.

Options:

1. (i), (iii), (iv)
2. (ii), (iii), (iv)
3. (i), (ii), (iii), (iv)
4. (ii), (iii)

Solution:

The spleen is indeed the graveyard for RBCs. Not all mammals have biconcave RBCs; for example, camels have oval RBCs. Clotting factors in plasma are present in an inactive form. Not all substances released by platelets are involved in clotting; some are involved in other processes like inflammation.
