What are the circular folds in the small intestines called?

The lining of the small intestine consists of a series of permanent spiral or circular folds, termed the plicae circulares, which amplify the organ’s surface area, promoting efficient nutrient absorption.

What is mucosal folds?

A mucosal fold refers to a fold in any mucous membrane in the body. This may refer to: Gastric fold of the gastric mucosa. Transverse folds of rectum in the anal canal. Circular folds in the small intestine.

What organs are around the stomach?

Mucous neck and pit cells: Produce mucin and bicarbonate to create a “neutral zone” to protect the stomach lining from the acid or irritants in the stomach chyme.

What is the function of parietal cells in the stomach?
