Body systems work together to keep the body healthy and the body systems are interdependent (they rely on each other).
The respiratory and circulatory systems work together to transport oxygen to the cells and remove carbon dioxide. The nervous and muscular systems work together to control movement. The endocrine and reproductive systems work together to regulate hormone production for reproduction.

Ill give you 3:skeletal,nervous,and muscular
By pressure.
Scienctist use experimentation through the scientific method and models to understand how systems work.
