Identify the vessels that lymph will pass through as it moves from the hindlimbs to the cardiovascular system:
1 Juncture of the external jugular/left subclavian vein
2 Thoracic duct
3 Cisterna chyli
4 Right lymphatic duct
A) 3, 4, 1
B) 4, 1
C) 1, 2, 3
D) 3, 2, 1
E) 2, 4, 1
Cisterna Chyli
A dilated sac at the lower end of the thoracic duct into which lymph from the intestinal trunk and two lumbar lymphatic trunks flows.
Cardiovascular System
The body's system comprising the heart and blood vessels, responsible for circulating blood to deliver oxygen and nutrients to tissues.
Thoracic Duct
The largest lymphatic vessel in the human body that drains lymph from the lower and left side of the body into the venous system.
- Identify the pathway lymph takes through the body from extremities to the cardiovascular system.
- Identify the specific vessels involved in the drainage of lymph from various body regions.

Final Answer :
D
Explanation :
Lymph from the hindlimbs first enters the lymphatic vessels and then flows into the cisterna chyli. From the cisterna chyli, it passes through the thoracic duct and then joins the left subclavian vein at the juncture of the external jugular vein. Therefore, the correct sequence of vessels is 3, 2, 1, making choice D the best answer.
