The small intestine is the primary site for digestion and nutrient absorption, while the large intestine primarily absorbs water and electrolytes from remaining indigestible material. The small intestine, with its extensive surface area created by folds, villi, and microvilli, secretes enzymes that break down carbohydrates, proteins, and fats into absorbable compounds. In contrast, the large intestine's main role is to absorb water and electrolytes, solidifying waste into feces and storing it for elimination. Bacteria in the large intestine also synthesize essential vitamins like K and B vitamins.12345
