Figure 34.11 Which of the following statements about the
- Chyme is a mixture of food and digestive juices that is produced in the stomach.
Introduction:
Digestive system is involved in the digestion of complex food substances into simpler ones with the alimentary canal and the glands associated with it.
Answer to Problem 1VCQ
Incorrect answer:
The incorrect answer is option (b) Food enters the large intestine before the small intestine.
Explanation of Solution
Explanation/justification for the incorrect answer:
Option (b)Food enters the large intestine before the small intestine. Food enters the small intestine where the complete digestion of food occurs, it is assimilated and then the undigested food reaches the large intestine for the reabsorption of excess water from it and elimination of the waste material through the anus. So, the incorrect answer is option (b).
Explanation for the correct answer:
Option (a) chyme is a mixture of food and digestive juices that are produced in the stomach. In the stomach, the digestion of the food is associated with the secretion of the gastric juice containing the pepsin and HCl. The partially digested food and the gastric juice is called the chyme. So, this is a correct option.
Option (c) in the small intestine, chyme mixes with bile, which emulsifies fats. The bile produced by the liver mixes with the chyme leading to the emulsification of the fats. So, this is a correct option.
Option (d) the stomach is separated from the small intestine by the pyloric sphincter. Pyloric sphincter is involved in the regulation of the chyme movement from the stomach to the small intestine. So, this is a correct option.
Thus, the pathway of digestion begins in the mouth, followed by the esophagus, stomach, small intestine, large intestine, and anus. Hence, the incorrect answer is option (b) food enters the large intestine before the small intestine.

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.
