This is not true. Almost all absorption occurs in the small intestine. The stomach simply uses its enzymes to break down food into smaller and smaller molecules. The most mechanical digestion occurs in the stomach due to the constant churning motion.
Absorption
Most of digestion occurs in the stomach and most absorption occurs in the small intestine.
Although the stomach is responsible for digestion, very little absorption happens in it. Instead, the stomach is more like a washing machine; it agitates foodstuffs. It stirs up ground up food (mechanical digestion from teeth / gums occurs in the mouth), with stomach acids in the stomach and bile salts from the gallbladder assisting in chemical digestion.
The second stage of digestion occurs in the stomach. Here, food is mixed with stomach acid and digestive enzymes to further break down proteins and begin the process of nutrient absorption.
Most chemical digestion occurs in the stomach and absorption occur in the intestines in humans and many other animals.
The digestive system.
Most nutrient digestion occurs in the stomach
The organ in the digestive system where the chemical breakdown of food primarily occurs is the stomach. Here, gastric acids and enzymes break down food into smaller particles for further digestion and absorption in the intestines.
Most protein digestion occurs in the stomach. However, further digestion of proteins also occurs in the small intestine.
Digestion occurs in the mouth, stomach and small intestine.
Digestion in the mouth accounts for about 5-10% of the total digestive process. The primary function in the mouth is mechanical breakdown through chewing, along with the enzymatic action of saliva, particularly the enzyme amylase, which begins the digestion of carbohydrates. Most digestion occurs in the stomach and small intestine, where further breakdown and absorption of nutrients take place.
