What is a system of organ systems working together called

The organs that work together is called systems. It is a group of parts or organs that interact and work together for a common purpose or function. Each of the parts seems to depend to each other in order to achieve their shared functions and goals. When one of the organs in a system becomes dysfunctional, automatically the other  parts cannot function as effective as they were during those times that everybody's in good condition becaus the condition of one organ in the system directly affects the others too.

Genetic engineering is the answer.
