The lining of the small intestine is composed of specialized cells called enterocytes, which are equipped with microvilli, tiny hair-like projections that significantly increase the surface area for absorption. These enterocytes are responsible for absorbing nutrients, such as amino acids, sugars, and fatty acids, from the digested food. The absorbed nutrients then enter the bloodstream to be transported to various cells throughout the body for use. Additionally, the small intestine's lining includes villi, which further enhance nutrient absorption by increasing the surface area.
