Which lymphatic trunks drain into the cisterna chyli?

• A. Intestinal trunks
• B. Lumbar trunks
• C. Intestinal trunks and lumbar trunks
• D. Subclavian trunks and jugular trunks

Answer: (C)

The cisterna chyli is an important reservoir in the lymphatic system, located in the abdomen. It serves as the collecting point for lymph from several lymphatic trunks before this fluid is transported to the thoracic duct and eventually returns to the bloodstream. The intestinal trunks are responsible for draining lymph from the gastrointestinal tract, particularly from the intestines, which includes chyle that is rich in fats after a meal. The lumbar trunks, on the other hand, drain lymph from the lower limbs, pelvis, and lower abdominal wall. Both of these trunks converge and feed into the cisterna chyli. Therefore, the correct choice indicates that both intestinal and lumbar trunks are involved in this drainage process, highlighting the importance of the cisterna chyli in collecting lymph from these significant anatomical areas. This is essential for the functioning of the lymphatic system, as it enables the body to efficiently process and transport lymph, including dietary lipids and immune cells, back into the circulatory system.
