Solution
During deglutition, also known as swallowing, the bolus (a mass of food that has been chewed and mixed with saliva) passes from the oesophagus into the stomach through the Lower Oesophageal sphincter. This is a muscular ring at the lower end of the oesophagus that controls the passage of food and prevents the stomach's acidic contents from flowing back into the oesophagus.
