In the human body, is every organ a part of only one organ system? Or are some organs a part of two or more organ systems?

I feel like in most cases, every organ in the organ system has only one specific function. But some organs may be a part of one or more organ systems. For example, the liver is a part of the digestive system but also plays an important role in the excretion system.

Hope this helps!

not sure if this what   you'r looking for would be percent composition
