4. When he eats, Eli chews his food carefully. As his teeth mash and crush the food, enzymes in his saliva break the food down into smaller molecules. What function is carried out by his saliva? • A. It is performing peristalsis. • B. It is chemically digesting the food. • C. It is mechanically digesting the food. • D. It is producing bile to break down fats.

8. Which of the following best explains an interaction between the digestive system and the respiratory system? • A. To use the energy in food broken down by the digestive system, the body needs oxygen obtained by the respiratory system. • B. The main function of the respiratory system is to control, coordinate, and regulate most of the functions of the digestive system. • C. Coordination between the respiratory and digestive systems is necessary because the digestive system obtains oxygen needed by the respiratory system. • D. The digestive system obtains nutrients from the food that is eaten, and the respiratory system transports the nutrients to the brain where they are needed.

14. Each organ of the digestive system plays an important role in food digestion. What is one role of the liver? • A. The liver is responsible for most mechanical digestion that occurs. • B. The liver produces bile, which helps break down fats into small droplets. • C. The liver transports food through the digestive tract through peristalsis. • D. The liver absorbs water from digested material before it moves to the rectum.
