Where does absorption of nutrients begin?

Understand the Problem

The question is asking about the initial site in the human body where the absorption of nutrients takes place, indicating a focus on human anatomy and physiology.

More Information

The small intestine is where the majority of nutrient absorption occurs. It has three parts: the duodenum, jejunum, and ileum, each of which plays a role in the absorption process.

Tips

A common mistake is thinking that digestion and absorption are the same processes. Digestion breaks down food, primarily starting in the mouth and continuing in the stomach, while absorption primarily occurs in the small intestine.
