- 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.Define peristalsis, and list the regions of the GI tract where it occurs. Be sure to mention segmentation in your answer.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.
- 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 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.The lack of adequate saliva due to the absence of or diminished secretions by the salivary glands is known as zerostomia. _____________________
- Oncospheres penetrate the small intestine mucosa and undergo development in to cysticerci in the lacteals of intestinal villi. What is a lacteal?

(Digestive or GI system is not a correct answer here)Histological description of the major organs of digestion and its coats or layers. Explain in a long explanation Layers of gallbladder: mucosa(inner layer of epithelium and loose connective tissue) a muscular layer perimuscular layer serosa(outer covering) The small and large intestinal wall has four layers: The outermost serosa muscularis submucosa innermost mucosa.Which of the following cells secretes the enzymes - gastric lipase and pepsin ogen? Group of answer choices neck mucous cells chief cells parietal cells enteroendocrine cells
- What different morphological adaptations exist to increase the surface area of the gastrointestinal tractWhich if the following is not a function of the digestive system 1. to ingest food 2. to digest food into small nutritions so that the molecules can pass through membrane 3. to absorb nutrient molecules 4. To eliminate indigestible remains 5. to deliver oxygen to Ty body tissuesProjections of the small intestinal mucosa that protrude into the lumen and increase the surface area are the: chordae tendineae plicae circularis haustra Peyer's patches
