Answer 1

Answer:

1.The small pieces of food get mixed with saliva by chewing is called a bolus. When food enters the digestive system by the mouth, it encounters a breakdown by the dental apertures and is then subjected to mixing with saliva which contains the amylase enzyme.

2.The enzyme that breaks down starch into sugar is called amylase. Salivary amylase is located in the mouth and is secreted in the saliva.

3.The longest part of the alimentary canal, the small intestine is about 3.05 meters (10 feet) long in a living person (but about twice as long in a cadaver due to the loss of muscle tone).
