Macronutrient Digestion Review: Begins in the mouth where the release enzymes, including specific to fat digestion, especially in infants, and specific to carbohydrate digestion. At this point, the bolus is swallowed and continues through the into the stomach. Here a hormone, called causes the release of which denatures protein and converts the bolus to which passes through the sphincter into the small intestine. Another hormone, sends a message to an accessory organ, which releases fluids including to decrease acidity, and several types of enzymes including specific to carbohydrate digestion, specific to fat digestion, and specific to protein digestion. Another hormone, sends a message to the gallbladder to release which emulsifies fats. Enzymatic digestion concludes and absorption begins through the found on the inner walls of the small intestines. Any items that cannot be absorbed such as fiber continue through the digestive track to the and out through the .
