Villi are tiny, finger-like projections lining the walls of the small intestine that play a crucial role in the digestive process. They increase the surface area for absorption, allowing for more efficient uptake of nutrients, vitamins, and minerals from digested food into the bloodstream. Each villus contains blood vessels and lymphatic vessels, which transport the absorbed nutrients throughout the body. By enhancing nutrient absorption, villi significantly contribute to overall digestive efficiency.
