Explanation: 

Detailed explanation-1: -Your esophagus is a hollow, muscular tube that carries food and liquid from your throat to your stomach. Muscles in your esophagus propel food down to your stomach. One of the most common symptoms of esophagus problems is heartburn, a burning sensation in the middle of your chest.

Detailed explanation-2: -Initially, the esophagus is lined by a simple columnar epithelial layer, which is gradually replaced by a stratified squamous tissue comprised a clearly distinct basal layer surrounded by the spinous, granulated, and cornified suprabasal layers.

Detailed explanation-3: -The laryngopharynx, also referred to as the hypopharynx, is the most caudal portion of the pharynx and is a crucial connection point through which food, water, and air pass. Specifically, it refers to the point at which the pharynx divides anteriorly into the larynx and posteriorly into the esophagus.
