What is gullet definition?

The gullet is the passage that leads from the mouth to the stomach in many animals, including humans. It is also known as the esophagus. Its primary function is to transport food from the mouth to the stomach through muscular contractions called peristalsis.

The gullet is a muscular tube that is approximately 25 centimeters long in humans. It is lined with a mucous membrane that secretes mucus to aid in the transport of food. The upper part of the gullet contains skeletal muscles that are under voluntary control, while the lower part contains smooth muscles that are under involuntary control.

The gullet has a sphincter muscle at both ends to prevent the backflow of stomach contents. The upper sphincter, called the upper esophageal sphincter, relaxes to allow food to enter the sarter of the gullet, while the lower sphincter, called the lower esophageal sphincter, relaxes to allow food to enter the stomach.

Several conditions can affect the gullet, including gastroesophageal reflux disease (GERD), esophagitis, and hiatal hernia. These conditions can cause inflammation, pain, and difficulty swallowing. Treatment may involve dietary changes, medications, or surgery.
