Final answer:
The heart is not an organ in the excretory system.

The heart is NOT an organ in the excretory system. The excretory system is responsible for eliminating waste products from the body. It consists of organs such as the kidneys, bladder, and ureter. The heart, on the other hand, is part of the circulatory system, which is responsible for pumping blood throughout the body.
