Question

Which term is used to describe fluids and food that are only partially digested?

Answers

  1. Chyme
    • Rationale:

      Simply stated chyme is partially digested food that is formed in the stomach. As the product of both chemical and mechanical digestion, it is a prerequisite for nutrient absorption.

  2. Ingestion
    • Rationale:

      Ingestion the process of taking fluid, food, or another substance into the body by swallowing or absorbing it. This is not the term used to describe fluids and food that are partially digested.

  3. Peristalsis
    • Rationale:

      Peristalsis is the wave-like movement that moves and propels fluids and food along the digestive tract with the help of muscles. This is not the term used to describe fluids and food that are partially digested.

  4. Mastication
    • Rationale:

      Simply stated, mastication is the process of chewing. This is not the term used to describe fluids and food that are partially digested.

Overview

Digestion is defined as the process of breaking down food by both enzymatic and mechanical action in the alimentary (i.e., gastrointestinal) canal into substances that can be used by the body via absorption.

Explanation

Learning Outcomes

As the food and fluids are refined in the stomach, they form chyme. Chyme is defined as partially digested food in the stomach. Chyme is the product of two forms of digestion (e.g., chemical and mechanical) and is a prerequisite for the absorption of nutrients.
