Explanation:
Detailed explanation-1: -The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.
Detailed explanation-2: -Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine.
