The body system responsible for returning excess tissue fluid to the cardiovascular system is the lymphatic system.

Explanation:

1. Lymphatic System Function: The lymphatic system is a part of the circulatory system and plays a vital role in maintaining fluid balance in the body. It collects excess interstitial fluid, which is the fluid that surrounds the cells in tissues, and returns it to the bloodstream, thus preventing swelling or edema.

2. How It Works: The lymphatic vessels transport lymph, a clear fluid that contains proteins and other substances, back to the cardiovascular system through the lymph nodes and eventually into the bloodstream at the thoracic duct.

3. Connection to Circulatory Health: By recycling this interstitial fluid, the lymphatic system is essential for ensuring that the fluids in the body are kept at optimal levels, supporting overall health and function.

In summary, the lymphatic system is the correct choice for the system that returns excess tissue fluid to the cardiovascular system.
