What happens to a meal of bread and fried eggs as it travels from the mouth to the stomach of a man?

Mouth/Teeth/Tongue


In the mouth, saliva adds moisture, while teeth tear and grind the bread and eggs into small pieces. The enzyme amylase is found in saliva. Amylase breaks down starches in the food. The tongue condenses the food particles into a ball that can be swallowed.

Esophagus


Swallowing food closes the epiglottis in the throat so that the windpipe is blocked as the food particles travel by. Food is moved towards the stomach by the contraction and relaxation of muscles in the esophagus. This process is called peristalsis


Stomach


Once the food reaches the stomach, chemicals such as hydrochloric acid and enzymes continue to break down the food particles for three to four hours. This turns the food particles into a substance called chyme. The chyme then moves through a valve at the bottom of the stomach and travels to the liver and gall bladder.
