Answer:
The pyloric sphincter is responsible for the movement of food from the stomach into the small intestine.
Step-by-step explanation:
The lower esophageal sphincter, or valve, controls food movement from the stomach into the small intestine.
This sphincter is located at the bottom of the esophagus, just above the stomach. Its main function is to prevent stomach acid and partially digested food from flowing back up into the esophagus. When we swallow food, the lower esophageal sphincter relaxes to allow it to enter the stomach.
After the food reaches the stomach, it is broken down by stomach acid and digestive enzymes. When the stomach is ready to empty its contents into the small intestine for further digestion and absorption of nutrients, the lower esophageal sphincter closes tightly to prevent the backward flow of stomach contents.
This valve is essential in preventing acid reflux, also known as heartburn. If the lower esophageal sphincter is weak or malfunctioning, stomach acid can flow back up into the esophagus, causing discomfort and damage to the lining of the esophagus.
In summary, the lower esophageal sphincter is the sphincter or valve that controls the movement of food from the stomach into the small intestine. It plays a crucial role in preventing acid reflux and maintaining the proper flow of food through the digestive system.
