What is cisterna chyli?

The cisterna chyli is a small sac-like structure located in the abdomen, near the base of the thoracic duct. It is part of the lymphatic system and serves as a storage area for lymph fluid before it is returned to the blood circulation.

The cisterna chyli receives lymphatic fluid from the lower part of the body, including the lower limbs, pelvis, and abdomen. The lymphatic vessels from these areas converge at the cisterna chyli, where the fluid is stored and filtered before continuing its journey through the lymphatic system.

From the cisterna chyli, the lymph fluid travels up the thoracic duct, a large lymphatic vessel that runs through the chest and drains into the left subclavian vein. This allows the lymph fluid to be returned to the bloodstream and circulated throughout the body.

Overall, the cisterna chyli plays an important role in maintaining the balance of fluid in the body and helps to remove waste and toxins from the tissues. It is a crucial part of the lymphatic system and contributes to overall health and immune function.
