18. The respiratory system depends on the nervous system for signals to A. Enhance the amount of available oxygen in the lungs B. Coordinate muscles controlling breathing. C. Release hormones to increase the exchange of gases. D. Exchange gases with the circulatory system. 19. How do nutrients absorbed by the small intestine travel to the individual cells of the human body? A. The nutrients are absorbed from the small intestine into the blood and move through the circulatory system to the body cells. B. The nutrients move from the small intestine directly to the liver and then move through the lymphatic system to the body cells C. The small intestine forces the nutrients into the kidneys, where the nutrients are then dissolved in fluids used by the body cells. D. The body cells send nerve impulses indicating a lack of nutrients to the small intestine, and the small intestine sends the nutrients back to the cells. 20.
