Question

Quizplus · Accepted Answer

The villi are specialized finger-like projections in the small intestine that increase the surface area available for nutrient absorption. The epithelial cells lining the villi have microvilli, which further increase surface area. Nutrients that have been broken down by digestive enzymes in the small intestine are absorbed across the epithelial cells of the villi and into the capillaries or lymphatic vessels beneath. The primary nutrients absorbed into the capillaries of the villi are glucose and amino acids, which come from the breakdown of carbohydrates and proteins respectively. Monoglycerides and fatty acids, which come from the breakdown of fats, are then packaged into triglycerides and transported by lymphatic vessels to the bloodstream. Therefore, choice C is the correct answer.
