VilliGroup of answer choicesgenerate movement of materials in the large intestine.are found throughout the gastrointestinal tract.contain both smooth and skeletal muscle fibers.increase surface area in the small intestine.All of the choices are correct
Answer: The VILLI (increase surface area in the small intestine).
Explanation:
Glucose, amino acids, fatty acids and glycerol, as well as , vitamins and minerals salts are absorbed in the small intestine. The walls of small intestine are specially adapted to carry out this function.
For efficient adsorption, a large surface area is necessary. The walls of small intestine have folds and furrows which serve to increase its surface area. These small finger-like projections are called the VILLI.
The inner surface layer or epithelium of each villus is thin; this allows the absorption of the end-products by either diffusion or active transport through it. There is a rich supply of blood vessels and lymphatic vessels containing blood and lymph respectively to carry away the absorbed food substances. In each villus( singular) , there is a blind lymphatic tube called a lacteal surrounded by a network of blood capillaries. The lymph in the lacteals transports carboxylic acids and glycerol which usually recombine to form fats again in the lacteals.
