The [answer2] is where ingestion of food occurs. The [answer3] transports food from the mouth to the stomach; no chemical digestion occurs. The [answer4] produces gastric juices which contain hydrochloric acid and the enzyme pepsin, which start the chemical breakdown of proteins. The [answer5] intestine is where most digestion and absorption occur. The [answer6] produces bile which helps to digest fats. The [answer7] stores, concentrates, and secretes bile into the small intestine. The [answer8] produces and secretes pancreatic juices which contain bicarbonate that neutralizes the acidity of the stomach-derived chyme and enzymes that further break down proteins, carbohydrates, and lipids.
