After digestion, chylomicrons from the small intestine are collected by the vessel

Options

A. thoracic duct
B. right lymphatic duct
C. lactiferous duct
D. right subclavian vein

Answer

To solve the question of which vessel collects chylomicrons from the small intestine after digestion, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chylomicrons**:
- Chylomicrons are lipoprotein particles that transport dietary lipids, primarily triglycerides, from the intestines to other locations in the body.

2. **Formation of Chylomicrons**:
- After the digestion of fats in the small intestine, the intestinal epithelial cells absorb these fats and package them into chylomicrons.

3. **Transport Mechanism**:
- Chylomicrons are too large to enter the blood capillaries directly. Instead, they enter the lymphatic system.

4. **Lymphatic System Role**:
- The lymphatic system plays a crucial role in transporting chylomicrons. They are collected from the small intestine and transported via lymphatic vessels.

5. **Identifying the Correct Vessel**:
- The chylomicrons are collected by specific lymphatic vessels. The options provided include:
- Thoracic duct
- Right lymphatic duct
- Lactiferous duct
- Right subclavian duct

6. **Correct Answer**:
- The correct vessel that collects chylomicrons from the small intestine is the **thoracic duct**. The thoracic duct is the main lymphatic vessel that drains lymph from the majority of the body, including chylomicrons from the intestines.

### Final Answer:
Chylomicrons from the small intestine are collected by the **thoracic duct**.
