Lymphatie vessels earry chylomierons into blood stream through

Options

A. right subclavian artery
B. postcaval vein
C. hepatic portal vein
D. left subclavian vein

Answer

**Step-by-Step Solution:**

1. **Understanding Chylomicrons:**
- Chylomicrons are lipoprotein particles that transport dietary lipids (fats) from the intestines to other locations in the body. They are formed in the intestinal cells after the digestion of fats.

2. **Role of Lymphatic Vessels:**
- Lymphatic vessels are responsible for transporting chylomicrons from the intestines into the bloodstream. They absorb the chylomicrons after the digestion and absorption of fats in the small intestine.

3. **Identifying the Pathway to the Bloodstream:**
- Chylomicrons enter the lymphatic system through specialized lymphatic vessels called lacteals, which are located in the villi of the small intestine.

4. **Options Analysis:**
- The question provides four options for how lymphatic vessels carry chylomicrons into the bloodstream:
- A) Right Subclavian Artery
- B) Post-Caval Vein (Vena Cava)
- C) Hepatic Portal Vein
- D) Left Subclavian Vein

5. **Evaluating Each Option:**
- **Right Subclavian Artery:** This artery supplies blood to the upper body but does not directly relate to the transport of chylomicrons.
- **Post-Caval Vein (Vena Cava):** This vein carries deoxygenated blood back to the heart but does not transport chylomicrons from the lymphatic system.
- **Hepatic Portal Vein:** This vein carries blood from the gastrointestinal tract and spleen to the liver, but it does not directly carry chylomicrons from the lymphatic system.
- **Left Subclavian Vein:** This vein is involved in receiving lymph from the lymphatic system, including chylomicrons, before they enter the bloodstream.

6. **Conclusion:**
- The correct answer is that lymphatic vessels carry chylomicrons into the bloodstream through the **Left Subclavian Vein**. This vein is where the lymphatic system drains its contents into the bloodstream.

**Final Answer:**
Lymphatic vessels carry chylomicrons into the bloodstream through the **Left Subclavian Vein**.
