Human Body System 

The human body is composed of several organ systems that all interact as a unit to ensure the body maintains functioning. You can find some major organ systems in the human body, each of which performs a different part in helping the body function.

Excretory and Reproductive Systems

Excretory and reproductive systems each have essential but various functions in animals. The excretory system keeps ion, water and nitrogen balance inside the body and removes wastes. The reproductive system generates new individuals of a species. Both excretory and reproductive systems are under endocrine control however are also influenced by the exterior environment.
