With the exception of alcohol and some drugs, the absorption of nutrients does not take place in the stomach. When the gastric content is completely mixed and liquefied, it passes into the small intestine. This is where more digestion of proteins, sugars, and fats happens and where the absorption of nutrients begins. By the time the contents pass through the entire small intestine to enter the colon, digestion is complete and the nutrients have been fully absorbed. The colon draws out water and some materials like vitamin K begin to form stool. This is a problem of the esophagus. The most common sign of this condition is heartburn. The circular muscle between the esophagus and stomach is the lower esophageal sphincter. This muscle always relaxes to let food in and air back up.
