The correct Answer is:
To solve the question regarding the statements about the spleen, we will analyze each statement one by one to determine which are correct. ### Step-by-Step Solution: 1. **Statement (i):** "Spleen is a large oval-shaped organ which mainly contains lymphocytes and phagocytes." - The spleen is indeed a large organ that contains a significant number of lymphocytes (a type of white blood cell) and phagocytes (cells that engulf and digest cellular debris and pathogens). - **Conclusion:** This statement is **correct**. 2. **Statement (ii):** "Spleen is a large reservoir of erythrocytes." - The spleen serves as a reservoir for red blood cells (erythrocytes) and is often referred to as the "graveyard" of red blood cells, where old or damaged erythrocytes are removed from circulation. - **Conclusion:** This statement is **correct**. 3. **Statement (iii):** "Spleen is a primary lymphoid organ." - The spleen is classified as a secondary lymphoid organ, not a primary one. Primary lymphoid organs (like the bone marrow and thymus) are where lymphocytes are produced and mature, while secondary lymphoid organs are where they become activated. - **Conclusion:** This statement is **incorrect**. 4. **Statement (iv):** "Spleen acts as a filter of the blood by trapping blood-borne microorganisms." - The spleen does function as a filter for the blood, trapping and destroying pathogens and blood-borne microorganisms. It plays a crucial role in the immune response. - **Conclusion:** This statement is **correct**. ### Final Evaluation: Based on the analysis: - Correct statements are (i), (ii), and (iv). - The incorrect statement is (iii). ### Answer: The correct options regarding the spleen are **(i), (ii), and (iv)**.
