Which of the following system returns the blood from intestine and breaks into portal system of capillaries in the liver ?

Options

A. Renal portal system
B. Hepatic porta system
C. Lymphatic system
D. Systemic circulation

Answer

To solve the question, we need to identify which system is responsible for returning blood from the intestine and breaking into a portal system of capillaries in the liver. Let's analyze the options provided:

1. **Renal Portal System**: This system primarily supplies blood to the renal tubules in the kidneys. Its main function is related to kidney filtration, not the intestine or liver.

2. **Hepatic Portal System**: This system specifically collects blood from the gastrointestinal tract (including the intestines) and spleen and directs it to the liver. In the liver, this blood breaks into a network of capillaries, allowing for the processing of nutrients and detoxification.

3. **Lymphatic System**: The lymphatic system is involved in transporting lymph, which contains white blood cells and helps rid the body of toxins and waste. It does not return blood from the intestines or connect to the liver.

4. **Systemic Circulation**: This system is responsible for delivering oxygenated blood to all tissues of the body and returning deoxygenated blood to the heart. It does not specifically deal with blood from the intestines to the liver.

Based on this analysis, the correct answer is:

**Hepatic Portal System**.

### Step-by-Step Solution:
1. **Identify the systems**: Look at each option provided (Renal Portal System, Hepatic Portal System, Lymphatic System, Systemic Circulation).
2. **Understand the functions**: Analyze the primary functions of each system to see which one relates to the intestines and liver.
3. **Narrow down the options**: Eliminate options that do not relate to the question (Renal Portal System, Lymphatic System, Systemic Circulation).
4. **Select the correct system**: Conclude that the Hepatic Portal System is the one that returns blood from the intestines and breaks into capillaries in the liver.
