Which of the following terms refers to taking in nutrients from food?

• A. Digestion
• B. Absorption
• C. Ingestion
• D. Metabolism

Answer: (B)

The correct answer is absorption because this term specifically refers to the process by which nutrients from digested food are taken into the body's circulatory system. After food is ingested and broken down during digestion, the nutrients—such as vitamins, minerals, carbohydrates, proteins, and fats—move through the intestinal walls into the bloodstream, making them available for use by the body’s cells. Ingestion refers to the initial act of taking food into the mouth, while digestion involves the mechanical and chemical breakdown of food into smaller components. Metabolism encompasses all the biochemical processes in the body, including how nutrients are converted into energy or used for building and repairing tissues. However, absorption is the specific step that follows digestion, where nutrients are absorbed into the body.
