Question

The esophagus, a tube that carries food to the stomach, is constantly being scraped as food travels through it. Why does the esophagus not deteriorate through a person’s lifetime? Cells can anabolize the food prior to entering the esophagus. Cells are constantly dividing and replacing old or damaged cells. Cells promote a fluid to build up along the esophagus to reduce friction. Cells build a type of protein called enzymes that act as an armor.

Answer 1

 Its not the first one for sure. All the other ones seem right. Sorry I couldn't be much help.

Answer 2

Answer:

Cells are constantly dividing and replacing old or damaged cells.

Explanation:

Although our bodies are highly coordinated and work accurately, the esophagus is constantly "scratched" by the food we eat. This degeneration of the esophagus needs to be fixed constantly and this is the role of epithelial cells.

Esophageal epithelial cells are responsible for the constitution of esophageal mucosa tissue. In their normal state, these cells grow and divide into new cells, which are formed as they are needed to replace defective cells. This process is called cell regeneration.
