2. a) The mouth is the beginning process it is located on your face. From the mouth it goes to the esophagus which is located down the throat the esophagus carries the food down to the stomach which is located in front of the liver. Stomach breaks down food and then enters the duodenum which is the first part of the small intestine. The center of your small intestine is right behind your belly button. Then the large intestine is located in the abdominal cavity. Then the anus is the rectum. b) After some research online I found the song I learned in 4th grade to help me remember the digestive system. (tune to row row row your boat:)

Mouth: Propulsion, chemical digestion and mechanical digestion Small intestine: Propulsion, absorption, chemical digestion and mechanical digestion Esophagus: Propulsion

Stomach: Propulsion, absorption, Chemical digestion, mechanical digestion Large Intestine: Propulsion, absorption chemical digestion

4. Absorption is the physiologic process by which molecules of food are taken from the gastrointestinal tract into the circulation. (Cherif, 2011 ) Propulsion is the movement of food along the digestive tract. The major means of propulsion is peristalsis, a series of alternating contractions and relaxations of smooth muscle that lines the walls of the digestive organs and that forces food to move forward. Chemical digestion is the chemical breakdown of food into simpler compounds. Proteins are broken...
