Where is the processes of swallowing?
Swallowing, or deglutition, primarily occurs in the throat (pharynx) and esophagus. The process begins in the mouth, where food is chewed and mixed with saliva, forming a bolus. The bolus then travels down the pharynx, where muscles contract to push it into the esophagus, and from there, it moves down to the stomach through coordinated muscle contractions known as peristalsis.
What does the pharynx have to do with your digestive system?
pharynx is an integral part of our digestive sytem.it allows the bolus of food we ingest to be swallowed and thus moved to the stomach for further processing.
What is the pharangyeal stage of deglutition?
The Pharyngeal stage of deglutition - the bolus hits the pharynx and triggers reflexes (from this point it is no longer voluntary) --> the soft palate is raised, the glottis closed and the pharynx shortened --> pharyngeal constrictors move bolus into the oesophagus

What is the part of the pharynx that is most actively and directly involved in the digestive process?
The part of the pharynx most actively and directly involved in the digestive process is the oropharynx. This section serves as a passageway for food and liquid from the mouth to the esophagus. It plays a crucial role in swallowing, where the muscles contract to push the food bolus down toward the esophagus, facilitating the transition from the oral cavity to the digestive tract.
Which structure helps move food to the pharynx?
The pharynx is the area immediately behind the mouth and nasal cavity before the oesophagus. The tongue is used to push the food towards the back of the throat to initiate the swallowing reflex. Swallowing reflex is initiated by touch receptors in the pharynx as a bolus of food is pushed to the back of the mouth by the tongue. Tongue
What muscle makes bolus?
The muscle primarily responsible for forming a bolus in the mouth is the tongue. The tongue's coordinated movements help manipulate food, mixing it with saliva to create a cohesive mass that can be easily swallowed. Additionally, the intrinsic and extrinsic muscles of the tongue work together to shape and propel the bolus towards the pharynx for swallowing.
What are the stages of deglutition?
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.
8 steps to get food from mouth to stomach?
# The food is chewed up and moistened with saliva to become a bolus, or a rounded mass of food. # The bolus is pushed to the back of the mouth by the tongue and the cheeks. # The soft palate and pendant uvula seal off the nasal cavity. # The tip of the tongue pushes up against the top of the mouth while the base of the tongue pushes the food down, and the sides of the pharynx contract. # The hyoid bone and the larynx are elevated. # The bolus pushes down on the epiglottis, which blocks the trachea. # A contraction of the pharynx pushes the bolus into the esophagus, past the larynx. # Another wave of contractions pushes the bolus through the esophagus to the stomach. The muscles of the neck and throat then relax and return to their normal breathing position
What is the involuntary reflex during swallowing?
the tongue rolling the bolus into the pharynx
The pharynx connects what two organs?
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.
What stage can we stop the process of swallowing a bolus of food?
We can stop the process of swallowing a bolus of food during the oral phase, which involves the voluntary act of moving food to the back of the mouth. Once the bolus enters the pharyngeal phase, swallowing becomes involuntary, and it is no longer possible to stop the process. The transition from the oral to the pharyngeal phase is marked by the triggering of the swallowing reflex.
