intestinal villi
Intestinal villi are tiny, finger-like projections that line the inner surface of the small intestine. They increase the surface area available for absorption, allowing nutrients from digested food to enter the bloodstream more efficiently. Each villus contains blood vessels and lymphatic vessels, which help transport these nutrients throughout the body.
The structure of intestinal villi is essential for proper digestion and nutrient absorption. They are covered with even smaller hair-like structures called microvilli, which further enhance the absorptive capacity. Together, these features play a crucial role in the digestive process, ensuring that the body receives the necessary nutrients from the food consumed.
