Answer: Small Intestine.
Step-by-step explanation: Digestion of the food is not completed without the absorption of food that we eat. Absorption of a majority of nutrients takes place in the small intestine, mostly in its jejunum part.
Only some vitamins and bile salts gets absorbed in the terminal of ileum. Rest all the nutrients are absorbed in the jejunum part of the small intestine using processes like passive diffusion.
Hence, maximum absorption of nutrients takes place in the small intestine.
