Final answer:
The cisterna chyli receives lymph from the lumbar and intestinal trunks, which then enters the thoracic duct to be transported into the bloodstream.
Step-by-step explanation:
The cisterna chyli is a crucial component of the lymphatic system, particularly within the context of the thoracic duct. This structure serves as a storage area for lymph coming from the lower regions of the body before it moves into the thoracic duct. Specifically, the cisterna chyli receives lymph from the lumbar and intestinal trunks, which collect lymph from the lower limbs, pelvis, and intestines. Therefore, the correct answer is that the cisterna chyli receives lymph from the lumbar and intestinal trunks. The thoracic duct, which commences at the cisterna chyli, then carries this lymph into the bloodstream, completing an essential part of the lymphatic drainage system.
