Given below are two statements about erythrocytes.
Statement (I): In the human foetus, the liver and spleen act as erythropoietic organs.
Statement (II): The old and worn out RBCs are destroyed in the liver and spleen and spleen is called the graveyard of RBC.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Foetal RBCs form in the liver and spleen, and old RBCs are destroyed in the liver and spleen.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept
RBC formation shifts from organ to organ with age, and old cells are removed by macrophages.

Step 2: Check Statement I
Before birth RBCs form first in the yolk sac and then in the liver and spleen. After birth red bone marrow takes over. Statement I is correct.

Step 3: Check Statement II
Old RBCs last about 120 days and are broken down in the liver and spleen. The spleen is called the graveyard of RBCs. Statement II is correct.

Final Answer:
Both Statement I and Statement II are correct. \[ \boxed{\text{(A) }\text{Both Statement (I) and Statement (II) are correct.}} \]
