The Digestive Journey: From Skittles in the Mouth to Nutrient Absorption in the Intestine

The process begins with chewing skittles in the mouth, where salivary amylase breaks down sugar. The bolus then travels down the esophagus via peristalsis into the stomach, further broken down by gastric juice. The pancreas releases enzymes like amylase and lipase to digest sugars and fats. Bile pro
