List two ways that food is changed in the digestive system?

Answer 1

Upon entry into the mouth, the enzymes within the saliva are already working on breaking down the food. The food then travels down the esophagus, where it continues to be broken down further, while the intestines and stomach pull the nutrients from the foods, and distribute them to the necessary units in order to keep the body functioning.

Answer 2

Much of the food consumed is chemically transformed, or digested. Breads are broken down by specific enzymes beginning in the mouth, and proteins come under attack by strong stomach acids for example.

Answer 3

As your food travels through your body, your food gets crushed by the mouth chewing then goes down to stomach and is turned into another matter by the stomach acid. It then comes out as fecal matter or waste.

Answer 4

Two categories of processes happen to food as it passes through the digestive system. Mechanical digestion breaks the food into smaller particles. Chemical digestion breaks down the particles into usable nutrients.

Answer 5

the food is now chopped carbohydrates become sugar; protein becomes acid

physically and chemically

Answer 6

Foods must be broken down into simpler substances that your body can use for raw materials and energy
