GENERAL HISTOLOGY

Detailed explanation-1: -The statement “The esophagus is digestive in function” is true. The esophagus is a muscular hollow tube that connects the mouth to the stomach, making it the second major organ in the digestive system if ordering by function.

Detailed explanation-2: -As a person swallows, food moves from the mouth to the throat, also called the pharynx (1). The upper esophageal sphincter opens (2) so that food can enter the esophagus, where waves of muscular contractions, called peristalsis, propel the food downward (3).

Detailed explanation-3: -Peristalsis squeezes your esophageal muscles from top to bottom. This pushes food and liquid along. If you could see peristalsis, it would look like a wave passing down your esophagus. To keep food and liquids moving in the right direction, your digestive tract has special muscles along its course called sphincters.

Detailed explanation-4: -Esophagus: The esophagus is a muscular tube that connects the pharynx (throat) to the stomach. The esophagus contracts as it moves food into the stomach.
