Kerckring folds, also called plicae circulares, are structures found in the small intestine. They are essentially circular or semicircular folds that help to increase the surface area of the intestine. These folds play a crucial role in absorbing nutrients from the food we eat.
They are located in the small intestine, specifically in the jejunum and ileum parts. These folds become less prominent as food moves through the digestive system.
Function of Kerckring Folds
The main function of Kerckring folds is to:
- Slow down food: This allows more time for the body to absorb nutrients.
- Increase surface area: More surface area means more space for absorbing vitamins, minerals, and other nutrients.
Stenosis is a medical term used to describe narrowing in a blood vessel, a valve, or a part of the body, which restricts normal blood flow or movement. It can happen in various parts of the body.
Types of Stenosis
