  5. What is DIGESTION? • Digestion is the process by which food is broken down into substances that can be used by the cells of the body. Table of Contents

  6. Two types of Digestion: MECHANICAL: food is broken down into smaller pieces (Example: chewing) CHEMICAL: food is chemically changed into simpler substances. (Example: food mixes with saliva) Click HERE to watch. Table of Contents

  8. Mouth “The place where food enters the body. The food is broken down both chemically and mechanically.” Tongue: helps to push the food to the back of the mouth where it is swallowed Return

  9. Esophagus “A muscular tube that connects the mouth to the stomach.” Peristalsis: the contraction and relaxation of the muscles in the esophagus/digestive tract that helps to move the food. Return

  10. Stomach “A ‘J-shaped’ sac that stores and further digests the food.” Bile: A digestive liquid found in the stomach that helps to break down the food. Return

  11. Small Intestine “A coiled, tube-like organ that absorbs the digested nutrients.” (Usually an average of 20 feet long.) Return

  12. Large Intestine “A large tube that absorbs most of the liquid from the undigested material.” Excretion is the process of removing wastes from the body. Return
