Answer:
The <u><em>pharynx</em></u> starts an involuntary swallowing action when senses food.The <u><em>esophagus</em></u> squeezes food down the digestive tract by an involuntary synchronized muscle movement called the <u><em>peristalsis</em></u>. Food that has been digested in the <u><em>stomach</em></u> is processed into a thick liquid called <u><em>chyme</em></u>.
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.
Question is a bit confusing but if i read it right there could be two answers:

Mitochondrion are the powerhouses of all cells. Obviously, you would need lots of power to move the muscles in your body. Therefore, muscle cells (myocytes) have a relatively large amount of mitochondria in order to provide enough energy to move the muscle, an essential life process.
This article from enotes explain how it interacts with ribosomes.
Its main job is to break down glucose into ATP (energy that the cell can use). The mitochondria does work with other cell organelles in that the ATP is dispersed throughout the cell to power the function of the cell. Specifically, the Ribosomes use the ATP to produce proteins in a process known as protein synthesis.
