Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The esophagus is the tube that food and liquid goes down after swallowing so it needs to be strong in order to withstand rough edges of food or hot liquid. What epithelial tissue is it lined with?

A	Pseudostratified Columnar
B	Stratified Cuboidal
C	Cartilage
D	Stratified Squamous

Explanation:

Detailed explanation-1: -Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food. Esophagus. After you swallow, peristalsis pushes the food down your esophagus into your stomach.

Detailed explanation-2: -The epithelium lining of the adult esophagus is squamous and stratified. However, in the early embryo when the esophagus is separated from the anterior foregut tube the epithelium is simple columnar.

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.
