Villi

Villi are small finger-like vascular projections, especially on the free surface of a membrane, such as the intestinal mucosa.

Villi line the inner surface of the small intestine and play an important role in the digestion process. Their large surface area allows for maximum absorption of nutrients into the blood.

In addition, the villi secrete various enzymes and secretions involved in the breakdown and digestion of food. They also protect the intestinal wall from mechanical damage and harmful microorganisms.

Violation of the structure and functions of the villi can lead to various diseases of the digestive system, so their condition is of great clinical importance.

The article describes the different types of villi and their functions in the human body. These small hairs are an important part of the digestive system and help in the absorption of nutrients. They also participate in protecting organs from external influences and promote heat exchange. This article talks about the different types of villi, what functions they perform and what diseases may be associated with their deficiency or excess. Each type of villi has its own specific role in the body, but they are all interconnected and interact with each other to ensure normal functioning.
