Questions & Step-by-Step Solutions

What is the primary role of the stomach in digestion?
  • Step 1: The stomach receives food from the esophagus after you swallow.
  • Step 2: The stomach mixes the food with gastric juices, which contain acids and enzymes.
  • Step 3: The mechanical action of the stomach muscles churns the food, breaking it down into smaller pieces.
  • Step 4: The chemical action of the gastric juices helps to further digest the food, breaking down proteins and killing harmful bacteria.
  • Step 5: The partially digested food, now called chyme, is prepared to move into the small intestine for further digestion and nutrient absorption.
