Final answer:
The intestinal trunks and lumbar trunks are the lymphatic trunks that drain into the cisterna chyli. The thoracic duct, which originates from the cisterna chyli, drains a much larger part of the body when compared to the right lymphatic duct.
Step-by-step explanation:
The lymphatic trunks that drain into the cisterna chyli are the intestinal trunks and the lumbar trunks. These structures play a crucial role in the transport of lymph from the lower parts of the body. The cisterna chyli serves as a sac-like chamber that collects lymph from the lower abdomen, pelvis, and lower limbs, which is then transported to the thoracic duct and into the left subclavian vein.
In the context of the lymphatic system, the thoracic duct is significant as it drains a much larger portion of the body compared to the right lymphatic duct, which only receives lymph from the upper right side of the body. The correct answer to the question is therefore, "Which of the lymphatic trunks drain into the cisterna chyli": C) Intestinal trunks and lumbar trunks.
