Solved in 2 steps
- The digestive juices from the liver are delivered to the. stomach liver duodenum colonParietal cells secrete ________. gastrin hydrochloric acid pepsin pepsinogenUsing the black lines shown in Figure 11.27, name the types of nutrient molecules present at each site that are small enough to be absorbed across the small intestines lining. Figure 11.27 Fill in the blanks for substances that cross the lining of the small intestine.
- Different regions of the digestive system specialize in ________ and _________ food and in __________ unabsorbed food residues.Figure 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.Figure 16.7 Which of the following statements about the digestive system is false? a. Chyme is a mixture of food and digestive juices that is produced in the stomach. b. Food enters the large intestine before the small intestine. c. In the small intestine, chyme mixes with bile, which emulsifies fats. d. The stomach is separated from the small intestine by the pyloric sphincter.
