Answer 2

The pharynx starts an involuntary swallowing action when senses food.The esophagus squeezes food down the digestive tract by an involuntary synchronized muscle movement called the peristalsis. Food that has been digested in the stomach is processed into a thick liquid called chyme.

Step-by-step explanation:

Digestion can be described as a process in which food is broken down so that an organism can use the energy in the food. The process of digestion is voluntary in the start as we take in food. But after this, the process of digestion becomes involuntary from the pharynx. The esophagus is the large tract through which food is squeezed into the stomach from the mouth. The squeezing is done by the force generated by muscle movements which is termed as peristalsis.
