Question 7 • 24 - 25 CR - Biology B (0411KB)

Which statements correctly describe the digestive system? Select four options.Food is cut into pieces in the mouth.Food becomes dry in the mouth.Proteins are broken down in the stomach.Carbohydrates are first broken down in the stomach.Food becomes mostly solid in the large intestine.Fat is broken down into smaller droplets in the small intestine.

Answer
A
Food is cut into pieces in the mouth.
B
Food becomes dry in the mouth.
C
Proteins are broken down in the stomach.
D
Carbohydrates are first broken down in the stomach.
E
Food becomes mostly solid in the large intestine.
F
Fat is broken down into smaller droplets in the small intestine.

Explanation

Food is mechanically cut and chewed in the mouth, and proteins begin to be digested in the stomach. Carbohydrate digestion starts in the mouth, not the stomach, and saliva makes food moist rather than dry. In the large intestine, water is absorbed, making waste more solid. Bile in the small intestine breaks fat into smaller droplets, so A, C, E, and F are correct.
