Question

Which substance is absorbed in the stomach for bodily use during the digestive process?

Answers

  1. Pepsin
    • Rationale:

      Pepsin is a digestive enzyme that is used during chemical digestion; however, it is not absorbed in the stomach for bodily use during the digestive process.

  2. Hydrochloric acid
    • Rationale:

      Hydrochloric acid is a digestive enzyme that is used during chemical digestion; however, it is not absorbed for bodily use during the digestive process.

  3. Fat soluble vitamins
    • Rationale:

      Fat soluble vitamins are not ingested for bodily use in the stomach during the digestive process. These vitamins, however, may be absorbed in the small intestine.

  4. Water soluble vitamins
    • Rationale:

      The stomach does provide for minimal absorption of some substances during the digestive process. Absorption of some water soluble vitamins (e.g., vitamin B and vitamin C) in addition to some medications (e.g., aspirin) occurs in the stomach.

Overview

Absorption is the process that occurs during the digestive process. During absorption, chemical digestion breaks chyme down into simple molecules that pass through the cell membranes of the stomach or small intestine’s lining into the blood or lymph capillaries for distribution throughout the body.

Explanation

Learning Outcomes

Minimal absorption occurs in the stomach during the digestive process. Some nutrients, however, are absorbed in the stomach as a result of chemical digestion. Specially, certain water soluble vitamins are absorbed in the stomach.
