Question

sort the different functions of the mouth and stomach. proteins are broken down. food is squeezed. food is mixed with acid. carbohydrates are broken down. food is cut into pieces. food becomes moist. mouth stomach

Explanation:

• Mouth functions: The mouth is where food is initially processed. Teeth cut food into pieces, saliva moistens food, and salivary amylase (an enzyme) starts breaking down carbohydrates. Also, the mouth doesn't squeeze food with acid (that's the stomach) or break down proteins (stomach starts protein breakdown with pepsin). So the functions for the mouth are: Food is cut into pieces, Food becomes moist, Carbohydrates are broken down.
• Stomach functions: The stomach has gastric acid, mixes food with acid, squeezes food (churning), and pepsin in the stomach breaks down proteins. So the functions for the stomach are: Proteins are broken down, Food is squeezed, Food is mixed with acid.

Answer:

• Mouth: Food is cut into pieces, Food becomes moist, Carbohydrates are broken down
• Stomach: Proteins are broken down, Food is squeezed, Food is mixed with acid
