INTESTINAL VILLUS Meaning and Definition

1. Intestinal villus refers to a small, finger-like projection found in the lining of the small intestine. The term "intestinal" signifies its location within the intestine, while "villus" indicates its shape resembling tiny hairs or finger-like structures.

   Intestinal villi play a crucial role in the absorption and digestion of nutrients in the digestive system. Each villus contains numerous blood vessels, as well as a lacteal, which is a specialized lymphatic vessel. Together, these structures facilitate the absorption of nutrients into the bloodstream or lymphatic system.

   The surface area of the small intestine is significantly increased by the presence of numerous intestinal villi. This increased surface area allows for more efficient nutrient uptake. This is because the villi provide an expanded surface over which the digested food can be absorbed. Additionally, the villi increase the contact time between the digestive enzymes and nutrients, promoting enhanced absorption.

   The inner surface of an intestinal villus is covered by specialized cells known as enterocytes. These enterocytes contain microvilli, which are even smaller projections on top of the villi. These microvilli further increase the surface area available for absorption.

   In summary, an intestinal villus is a tiny, finger-like projection found in the small intestine. It possesses an extensive network of blood vessels and a lacteal, which contributes to the absorption of nutrients. Intestinal villi significantly increase the surface area available for nutrient absorption, thereby facilitating efficient digestion and absorption in the small intestine.

Etymology of INTESTINAL VILLUS

The word "intestinal" comes from the Latin term "intestīnus", meaning "internal" or "inner". It is derived from the Latin word "intus", meaning "within".

The term "villus" also has Latin roots. It is derived from the Latin word "villum", which refers to a tuft of hair or a shaggy fleece. The term "villus" specifically refers to the minute structures that line the surface of certain organs or tissues in the body.

Therefore, "intestinal villus" refers to the tiny, hair-like structures found on the inner surface of the intestines.
