Most of the absorption of nutrients occurs in the small intestine.
The correct answer is the small intestine. To determine this, you can recall the basic anatomy and physiology of the digestive system. The process of nutrient absorption occurs after food particles have been broken down into smaller molecules through digestion. The small intestine is the portion of the digestive system where the majority of absorption takes place. It is specialized for nutrient absorption due to its long length, large surface area, and presence of numerous microscopic finger-like projections called villi, which further increase its surface area for absorption. The stomach primarily serves as a storage organ for partially digested food and does not have a significant role in nutrient absorption. The large intestine primarily absorbs water and electrolytes from the remaining indigestible material. The mouth is responsible for the initial mechanical and chemical breakdown of food but is not involved in nutrient absorption. Therefore, the small intestine is the correct answer.
