- 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.arrow_forwardFigure 34.19 Which of the following statements about digestive processes is true? Amylase, maltaseT and lactase in the mouth digest carbohydrates. Trypsin and lipase in the stomach digest protein. Bile emulsifies lipids in the small intestine. No food is absorbed until the small intestine.arrow_forwardFigure 34.12 Which of the following statements about the small intestine is false? Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food. The inside of the small intestine has many folds, called villi. Microvilli are lined with blood vessels as well as lymphatic vessels. The inside of the small intestine is called the lumen.arrow_forward
