What are some of the connections between human body systems? Give some examples of how they work together.

Can you do a paragraph (5 sentences) please? thank you!

For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it. Each of your body systems relies on the others to work well.
