Digestion in the stomach involves mainly the breakdown protein.
There is very little digestion of the other nutrients in the stomach.
Stomach acid is so strong that the lining of the stomach must secrete a thick, slimy mucus to prevent damage to the stomach itself.
No food is acidic enough to make stomach acid stronger.
From the stomach, the food proceeds to the small intestine.
The fluid in the small intestine is neutral, with a pH of about 7. This environment is needed for the action of intestinal enzymes.
In the small intestine, carbohydrates and fats are digested.
The proteins are further broken down.
The products formed by the breakdown of carbohydrate, fat, and protein are absorbed through the walls of the small intestine.
Vitamins and minerals are mostly without being chemically changed.
Fiber, some water a few mineral sarts, and the wastes of digestion move to the large intestine.
There, the mineral salts are absorbed, as is some of the water.
The remaining materials are excreted.
Digestion is the first step in the process of nourishing the body.
Many complex chemical changes occur during digestion. The regulation of pH is a critical factor in the successful digestion of food.
