Explanation

Cisterna chyli is a dilated sac at the lower end of the thoracic duct into which lymph from the intestinal trunk and two lumbar lymphatic trunks flow. It receives fatty chyle from the intestines and thus, acts as a conduit for the lipid products of digestion. It is the most common drainage trunk of most of the body's lymphatics.
