Figure 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.

Describe the ENTIRE process of both chemical AND mechanical digestion from mouth to anus of all of the nutrients in this candy (hint: there are carbs/fats/and proteins present). Your response must include the passing of the candy through all major organs and the role of accessory organs. You must also include key enzymes involved in breaking down each nutrient type AND include key words like bile, chyme, bolus, etc.
