B. Bean-shaped organ
C. Contains phagocytes only
D. Taps blood- borne micro oganisms

Answer

To determine which statement about the spleen is incorrect, we will analyze each option provided:

1. **Option A: Secondary lymphoid organ**
- The spleen is indeed classified as a secondary lymphoid organ. Secondary lymphoid organs are where lymphocytes (a type of white blood cell) are activated and proliferate. This statement is correct.

2. **Option B: Bean-shaped organ**
- The spleen is commonly described as a bean-shaped organ due to its anatomical shape. This statement is also correct.

3. **Option C: Contains phagocytes only**
- This statement is incorrect. While the spleen does contain phagocytes (cells that engulf and digest pathogens), it also contains lymphocytes, which are crucial for immune responses. Therefore, this statement is not true, as the spleen contains both phagocytes and lymphocytes.

4. **Option D: Taps blood-borne microorganisms**
- The spleen functions to filter the blood and trap blood-borne microorganisms, which is a correct description of its role in the immune system.

After evaluating all the options, we conclude that the incorrect statement is:

**Answer: Option C - Contains phagocytes only.**
