What will happen to the body of an adult man if the spleen is removed ?

Options

A. WBC production will be lowered
B. RBC production will be lowered
C. Antibody production will be less
D. Filtration of dead RBC will not be there

Answer

### Step-by-Step Text Solution:

1. **Understanding the Spleen's Function**: The spleen is an important organ in the body that plays a crucial role in the immune system and blood filtration. It helps in filtering out old and damaged red blood cells (RBCs) and also stores blood.

2. **Effects of Spleen Removal (Splenectomy)**: When the spleen is surgically removed (a procedure known as splenectomy), several changes occur in the body:
- The immune system may become compromised, as the spleen is involved in the production of certain immune cells and antibodies.
- The body may have difficulty filtering out dead or damaged RBCs, leading to an accumulation of these cells in the bloodstream.

3. **Analyzing the Options**:
- **Option 1**: "WBC production will be lowered." - This is incorrect. The production of white blood cells (WBCs) is not significantly affected by spleen removal, as it primarily occurs in the bone marrow and is stimulated by factors like granulocyte colony-stimulating factor.
- **Option 2**: "RBC production will be lowered." - This is also incorrect. The production of red blood cells is regulated by erythropoietin, which is produced by the kidneys and is not directly influenced by the spleen.
- **Option 3**: "Antibody production will be less." - This statement is misleading. While the spleen does play a role in the immune response, the overall antibody production is not solely dependent on the spleen.
- **Option 4**: "Filtration of the dead RBC will not be there." - This is the correct option. The spleen is responsible for filtering out old and damaged RBCs, and without it, this function is impaired.

4. **Conclusion**: The primary consequence of spleen removal in an adult man is the impaired filtration of dead RBCs, leading to potential complications such as an increased risk of infections and accumulation of old blood cells.
