1. Through which organs, and in what order does the bolus of food travel?
• The bolus of food first travels to the oral cavity, pharynx, esophagus, stomach, small intestine, and then to the large intestine.

2. How long does the food remain in each segment of the digestive tract and what physiological processing takes place during this time?
• Chemical and mechanical digestion begins in the oral cavity. Temperature, taste, texture are sensed, and the saliva helps the chemical digestion because it is secreted by the salivary glands. The breakdown of the enzymes in the saliva helps the food to be swallowed. The mechanical breakdown of the food is from the teeth, and when the food is swallowed, the pharynx is where the food is passed. The oral cavity and esophagus are connected because of the pharynx. The food is moved down to the stomach by the esophagus, so the bolus is in the stomach. Acting as a storage organ, breaking down the bolus mechanically, and secreting

Rice is a carbohydrate and it is the body’s preferred source of energy. Digestion starts in the mouth because of chewing, and it mechanically breaks down the food into smaller pieces. What are present in saliva are enzymes like amylase, which helps in the digestion of carbs. Carbs that are partially digested go to the esophagus and then to the stomach. From the stomach the carbs go to the small intestine where sugars are broken down and then absorbed into the blood stream. Chicken is a protein with just a little bit of fat. Large molecules of the protein need to be digested by enzymes before our body can use the protein to help with repairing and building of the tissues. The stomach is where the digestion of proteins begins, and when they are converted to amino acids, it can be absorbed into the bloodstream and then transported through the body. The body used the calories from the food to help with energy and
