Homeostasis depends upon the proper interactions of the various body systems. For example, the cardiovascular system and respiratory systems depend upon each other to carry oxygen to the cells of the body. The cardiovascular system transports blood to the tissue and to the lungs, while the respiratory system exchanges oxygen for carbon dioxide in the blood being transported to the lungs. If the blood was not properly transported to the lungs, cells would not receive oxygen even though blood might still flow to the tissues containing those cells.
Describe the interrelationship between two body systems of your choice. Give three examples of how they work together.
