define bolus and chyme
Answers
Answer:
A bolus is a ball-like mixture of food and saliva that forms in the mouth during the process of chewing. It has the same color as the food being eaten, and the saliva gives it an alkaline pH. Under normal circumstances, the bolus is swallowed, and travels down the esophagus to the stomach for digestion.
Chyme, a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and intestine during digestion. In the stomach, digestive juices are formed by the gastric glands; these secretions include the enzyme pepsin, which breaks down proteins, and hydrochloric acid.
Answer:
BOLUS:a small rounded mass of a substance, especially of chewed food at the moment of swallowing.
CHYME:the pulpy acidic fluid which passes from the stomach to the small intestine, consisting of gastric juices and partly digested food.
