What is the enlarged, pouch-like structure in the abdomen that serves as a storage area for lymph called?

Cisterna chili
Thoracic duct
Lymph node
Spleen

The correct answer is: Cisterna chili

The enlarged, pouch-like structure in the abdomen that functions as a storage area for lymph is known as the cisterna chyli. This structure is an important part of the lymphatic system; it is located at the lower right side of the thorax, where it collects lymph from the lower body before it drains into the thoracic duct. The cisterna chyli acts as a reservoir for lymph fluid, which contains fatty acids and other substances. This storage capability is crucial for the effective transport of lymph back into circulation. The thoracic duct, which collects lymph from the cisterna chyli, then carries this fluid to the left subclavian vein, enabling the reintroduction of lymph into the bloodstream. Other structures mentioned have different functions: the thoracic duct is the main conduit for lymph transport, lymph nodes serve as filtration points for pathogens and foreign material, and the spleen plays a role in filtering blood and immune response, rather than storing lymph.
