Explanation:

The Principle of Life is an integrated system of biological facts that summarizes the truth about biology. There are Twelve Principles of Life of biology in total. And each principle defines a fact and establishes the universal truth about a life.

If we summarize the lines 'body systems work with each other in highly related ways. They perform functions that no one system could do alone' to the principles of life, it can be summarized to the principle of 'Life is Internally Integrated.'

By this principle, it established the fact that body systems works with each other in highly related ways. Each system performs a function which cannot be done without the help of another system.
