Pharyngeal constrictor muscles (superior, middle and inferior)
Peristalsis is the wavelike motion of muscles that pushes food downward through the digestive tract. It helps propel food and liquids from the esophagus to the stomach and through the intestines for digestion and absorption.
The esophagus has two types of muscles. The upper third of the esophagus is composed of striated muscles, while the lower third contain smooth muscles. The muscles in the middle are a mixture of both striated and smooth.
As a simplified response, muscles in the tongue pushes food into the pharynx. However, it's a little more complicated than that. This address has good info on your question: http://www.nature.com/gimo/contents/pt1/full/gimo1.html
Food is pushed down the esophagus by a series of rhythmic muscle contractions called peristalsis. As food enters the esophagus, the muscles in the walls of the esophagus contract and relax in a coordinated manner to propel the food towards the stomach. The esophagus also has a sphincter at its lower end that opens to allow food to enter the stomach.
Peristalsis is a rhythmic contraction of a tubular organ, such as the intestines or esophagus, to propel its contents along the length of the organ. This coordinated muscular movement helps move food, liquid, or waste through the digestive or urinary system.
The muscular funnel you are referring to is the pharynx. It serves as a common passageway for both air from the nasal cavity and food from the oral cavity to enter the esophagus and trachea respectively. Muscles in the pharynx contract to help propel food and liquid into the esophagus during swallowing.
The skeletal muscles of the pharynx play a crucial role in initiating peristalsis, which is the coordinated contraction and relaxation of muscles that propel food through the digestive tract. During swallowing, the pharyngeal muscles contract sequentially, pushing the food bolus down into the esophagus. This action creates a wave-like motion that facilitates the movement of food, ensuring it moves efficiently from the mouth to the stomach. Additionally, the skeletal muscles enable voluntary control during the initial phases of swallowing before the process becomes involuntary in the esophagus.
Oesophagus, portion of the digestive tube that conducts food from the mouth to the stomach. When food is swallowed it passes from the pharynx into the esophagus, initiating rhythmic contractions (peristalsis) of the esophageal wall, which propel the food along toward the stomach. Pharynx, area of the gastrointestinal and respiratory tracts which lies between the mouth and the oesophagus.
Peristalsis is the wavelike motion of muscles that pushes food downward through the digestive tract. It helps propel food and liquids from the esophagus to the stomach and through the intestines for digestion and absorption.
The Esophagus is the food tube that passes a chewed food and saliva packet called a bolus, from the mouth down to the stomach. The trachea is the passageway from the mouth to the lungs. Your trachea allows you to breath air in. Google image search should give you some anatomy pictures.

The esophagus is a muscular tube that only transports food and liquids from the mouth to the stomach through a series of contractions called peristalsis. Its main function is to propel food bolus to the stomach for further digestion and absorption.

Deglutition, or swallowing, consists of three stages: oral, pharyngeal, and esophageal. During the oral stage, the food is chewed and formed into a bolus before being voluntarily pushed to the back of the mouth. In the pharyngeal stage, the swallow reflex is triggered to move the bolus through the pharynx and into the esophagus. Finally, in the esophageal stage, peristalsis helps transport the food down the esophagus and into the stomach.
Peristaltic movements are wave-like contractions of the muscles in the esophagus, stomach, and intestines that help propel food and nutrients through the digestive system. These movements are essential for moving food along the digestive tract and facilitating digestion and absorption of nutrients.
