How many nutrients are absorbed in the duodenum according to the text?

The correct answer is based on the understanding that the duodenum, which is the first section of the small intestine, plays a critical role in nutrient absorption. It is specifically responsible for the absorption of several key nutrients that are vital for the body's functioning. In the context of the information provided in the text, 8 nutrients are identified as being absorbed in the duodenum.

These nutrients often include a range of macronutrients and micronutrients such as carbohydrates, proteins, fats, vitamins, and minerals that have undergone initial digestion. The duodenum is also the site where pancreatic enzymes and bile are introduced, facilitating the breakdown and subsequent absorption of these nutrients. Understanding the specific nutrients absorbed in the duodenum is important for grasping the overall process of digestion and nutrition in pediatrics, highlighting the significance of this intestinal segment in health and disease management.
