Answer:
carbohydrates changed into sugar
proteins broken down to amino acids
fats converted to fatty acids
nutrients carried to cells
Explanation:
The first step in digestion takes place in the mouth. Saliva contains a digestive enzyme that begins the change of carbohydrates into sugar. Then the sugar can dissolve. The other kinds of nutrients taste good, and your teeth grind them up, but digestion of protein and fat has not begun.
The esophagus is the tube leading from your mouth to your stomach. Your esophagus has ring-like muscles that squeeze the food and push it down into your stomach.
The stomach has thick walls of muscles that squeeze and churn the food into a thick, pasty lump. The stomach makes enzymes and other chemicals; and, as it churns, it continues the process of digestion.
Your food, by now, is in a very liquid state. Saliva from your mouth and stomach and such chemicals as hydrochloric acid (HCl) and pepsin have begun to break down protein. Fats are not broken down until they reach the small intestine.
After food is broken down and partially dissolved in the stomach, the stomach muscles push the food on into the small intestine. Two small organs, the gall bladder and the pancreas produce enzymes that enter the small intestine in small amounts and complete the digestion of your food.
Your food is now completely liquid and contains amino acids from the proteins, digested fats called fatty acids and glycerin, and simple sugars--mostly glucose. Vitamins and minerals do not change. They are in the digested liquid and pass directly into the bloodstream.
