Esophagus The esophagus (American English) or oesophagus (British English), commonly known as the foodpipe or gullet, is an organ in vertebrates which consists of a fibromuscular tube through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.

- ANSWER   The esophagus is the conduit between the mouth and the stomach. It contains a muscular wall that can contract rhythmically to propel food from the mouth on down, … a process called peristalsis. The esophagus is like a muscular tube about 25 cm long between the throat and the stomach.

Review The main function of the esophagus is to propel swallowed food or fluid into the stomach. This occurs through sequential or peristaltic contraction of circular muscle in the esophageal body, in concert with appropriately timed relaxation of the upper and lower esophageal sphincters.sophageal peristalsis consists of sequential contraction of the circular muscles of the muscularis propria, which is largely mediated by acetylcholine. This sequential contraction serves to occlude the esophageal lumen and push the bolus aborally.

What is the role of the esophagus in the digestive system? While the esophagus is moving things along, it also has to keep things from backing up (regurgitating) and re-entering the throat. That's where another gatekeeper, known as the upper esophageal sphincter, comes into play. The two sphincters, upper and lower, make sure the food doesn't back up in the wrong direction.

Esophagus The esophagus (American English) or oesophagus (British English), commonly known as the foodpipe or gullet, is an organ in vertebrates which consists of a fibromuscular tube through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.he esophagus is innervated by the vagus nerve and the cervical and thoracic sympathetic trunk. The vagus nerve has a parasympathetic function, supplying the muscles of the esophagus and stimulating glandular contraction. Two sets of nerve fibres travel in the vagus nerve to supply the muscles.

Clinical investigations include X-rays using barium, endoscopy, and CT scans.

RocketSwag.com How Does The Esophagus Work ? The esophagus is an important organ of the digestive system. Derived from Latin vocabulary, this term means “what carries and eats”. This 25 to 30-centimeter long tube extends from the oral cavity to the stomach passing via an opening in the diaphragm. The esophagus is distinguished into three segments, namely cervical, thoracic and abdominal.

Chapter 27: The esophagus, stomach and intestines Abdominal part of esophagus. After its cervical and thoracic course, the esophagus traverses the diaphragm and joins the stomach at the gastro-esophageal junction. The junction is a barrier to the reflux of contents from the stomach back into the esophagus. A complicated sphincteric segment extends several centimeters above the gastro-esophageal junction and is partly in the thorax, partly in the diaphragm, and partly in the abdomen.

Esophagus At the superior end of the esophagus is the upper esophageal sphincter that keeps the esophagus closed where it meets the pharynx. The upper esophageal sphincter opens only during the process of swallowing to permit food to pass into the esophagus.

- The esophagus is a muscular tube connecting the throat (pharynx) with the stomach. The esophagus is about 8 inches long, and is lined by moist pink tissue called mucosa. The esophagus runs behind the windpipe (trachea) and heart, and in front of the spine.

- Email Article. Esophagus. The esophagus is a small hose-like tube, which connects the mouth to the stomach. As it leaves the mouth, the esophagus follows a straight path through the neck and chest, passing near the heart through the diaphragm muscle and finally entering the stomach.

Swallowing Disorders Next, the tongue pushes the food from the mouth to the throat (pharynx). The voice box (larynx) closes so no food can enter the breathing passages or lungs. Finally, a special muscle called a sphincter, located where the throat and esophagus join, opens so the food can move into the esophagus. Esophageal phase of swallowing. The esophagus is a tube-like organ that connects the mouth and throat with the stomach. At each end, the tube is closed by the contraction of special muscles called sphincters. The esophagus and sphincter muscles are designed to move what is swallowed to the stomach. They also prevent stomach contents from moving back up into the esophagus and breathing passages. Food that enters the esophagus is squeezed down to the stomach by a special muscle contraction called peristalsis.

- The LES normally helps prevent food from flowing backwards, from the stomach into the esophagus. The LES should relax in response to swallowing to allow food to enter the stomach. In patients with achalasia, the LES fails to relax, creating a barrier that prevents food and liquids from passing into the stomach.

Barrett's Esophagus Normal Function. The esophagus seems to have only one important function in the body-to carry food, liquids, and saliva from the mouth to the stomach. The stomach then acts as a container to start digestion and pump food and liquids into the intestines in a controlled process.

The Esophagus Anatomically and functionally, the esophagus is the least complex section of the digestive tube. Its role in digestion is simple: to convey boluses of food from the pharynx to the stomach. The esophagus begins as an extension of the pharynx in the back of the oral cavity.

Esophagitis & Stricture The esophagus is the food tube, or gullet, that carries food and liquid from the mouth to the stomach. The stomach churns the food and secretes a strong acid that aids in digestion. A specialized muscle, known as the lower esophageal sphincter (LES), is located at the end of the esophagus.

Esophagus The esophagus is a fibromuscular tube, about 25 centimetres long in adults, which travels behind the trachea and heart, passes through the diaphragm and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs.

Esophagus The esophagus is a hollow muscular tube that transports saliva, liquids, and foods from the mouth to the stomach.When the patient is upright, the esophagus is usually between 25 to 30 centimeters in length, while its width averages 1.5 to 2 cm.he esophagus passes close to the trachea (breathing tube) and the left side of the heart. This means that problems with the esophagus, such as eating something too hot, can sometimes feel like a pain close to or in the heart or throat.

esophageal ESOPHAGUS: (as seen through an endoscope) The muscular tube, about 10 to 12 in (25 to 30 cm) long, that carries swallowed foods and liquids from the pharynx to the stomach. In the upper third of the esophagus, the muscle is striated; in the middle third, striated and smooth; and in the lower third, entirely smooth. Peristalsis is regulated by the autonomic nervous system.
