Options

A. to control blood pressure
B. to assist liver
C. to act as a hemopoietic tissue
D. to assist kidneys

Answer

To solve the question regarding the function of the largest lymphatic organ in humans, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Largest Lymphatic Organ**:
- The largest lymphatic organ in the human body is the spleen.

2. **Understand the Functions of the Spleen**:
- The spleen has several important functions:
- It is involved in the production and maturation of white blood cells (WBCs), which are crucial for the immune response.
- It filters the blood, removing old or damaged red blood cells (RBCs) and platelets.
- It acts as a reservoir for blood and can release stored blood in case of hemorrhage.
- It plays a role in the hemopoietic process, which is the formation of blood cellular components.

3. **Clarify the Hemopoietic Function**:
- The spleen is considered a hemopoietic tissue because it is involved in the production of blood cells, including RBCs, WBCs, and platelets, especially during fetal development.

4. **Eliminate Incorrect Options**:
- The spleen does not control blood pressure, assist the liver, or assist the kidneys directly, which helps narrow down the correct function.

5. **Conclude the Correct Answer**:
- Based on the functions discussed, the primary function of the spleen as the largest lymphatic organ is related to its role in immune response and blood filtration.

### Final Answer:
The function of the largest lymphatic organ in man (the spleen) is to produce and mature white blood cells, filter blood, and act as a hemopoietic tissue.
