Put the phrases in the order in which they occur in the human body during digestion. absorption of glucose in blood physical breakdown of food in your mouth pepsin action peristalsis in stomach carbohydrate breakdown by salivary amylase

This is a bit tricky. I'm sure with the first and second step, but the 3-5 should happen at the same time.

1. physical breakdown of food in your mouth
This is when you are chewing your food. The food is cut by teeth into smaller pieces so its surface area is bigger and digestion can happen faster.

2. carbohydrate breakdown by salivary amylase 
Saliva in mouth has amylase enzyme. Chewing will increase the saliva and the enzyme will break down a part of carbohydrate in the food.

3. pepsin action
The stomach is producing pepsinogen that will change into pepsin which could digest protein.

4. peristalsis in stomach
The stomach will moves for 1-2 hour before letting the food go into the small intestine. The movement will stir and grind the food, make the enzyme spread so digestion can happen faster.

5. absorption of glucose in blood
Most glucose is absorbed in intestine, so I think it should be last
