During which phase are nutrients absorbed into the bloodstream?
Understand the Problem
The question is asking which phase of digestion is responsible for the absorption of nutrients into the bloodstream. This relates to the study of the digestive system and its functions.
Answer
Small intestine, especially jejunum and ileum.
Nutrients are absorbed into the bloodstream primarily in the small intestine, particularly in the jejunum and ileum.
Answer for screen readers
Nutrients are absorbed into the bloodstream primarily in the small intestine, particularly in the jejunum and ileum.
More Information
Nutrient absorption primarily occurs in the small intestine, where digested food molecules are absorbed through villi and enter the bloodstream. This process is crucial for distributing nutrients throughout the body.
Tips
Sometimes people confuse the stomach with the small intestine for nutrient absorption. The stomach is mainly for digestion, not absorption.
