Answer 1

In the mouth, Hamburger is bitten and broken down by the teeth and salivary amylase is secreted from the salivary glands to moisten the food and is turn it into a bolus, a soft moist mass of food which is easy to swallow.

• Next, the bolus passes thru the pharynx the region at the back of the mouth.
• The bolus travels down the esophagus, a long narrow muscular tube, via peristalsis (rhythmic contractions) on its way to the stomach.
• Before the food enters the stomach, it passes through the esophageal sphincter.

In the stomach, the bolus mixes with hydrochloric acid in the stomach to aid in chemical digestion.

• The stomach is lined with a thick coat of gastric mucosa to protect it from the digestive enzyme in the gastric juice.
• The bolus leaves the stomach via pyloric sphincter, and now the bolus has been transformed into a semiliquid paste called chyme.
• The chyme enters into the duodenum of the small intestine. This is the region of the small intestine that receives secretions from the pancreas and the liver.
