a. Hormones that reduce gastric acidity
b. Liquefied food ready for digestion
c. Nutrients after being absorbed
d. Secretions that help digest food
ANS: B
Before being digested, food must be broken down into a liquid form. This liquid is called chyme. Secretin is the hormone that inhibits acid production and decreases gastric motility. Absorption is carried out as the nutrients produced by digestion move from the lumen of the GI tract into the body's circulatory system for uptake by individual cells. The secretions that help digest food include hydrochloric acid, bile, and digestive enzymes.
