Did you mean 'bag like organ' The stomach is part of the digestive system, which is sometimes called the gastrointestinal tract. It is a muscular, bag-like organ which lies between the lower end of the gullet (oesophagus) and the beginning of the small bowel (small intestine). Once food has been swallowed it passes down the gullet and into the stomach. Both ends of the esophagus are closed off by muscular constrictions known as sphincters; at the anterior, or upper, end is the upper esophageal sphincter, and at the distal, or lower, end is the lower esophageal sphincter. The cardia (also known as Z-line or esophagogastric junction or gastroesophageal junction) is the anatomical term for the junction orifice of the stomach and the esophagus. At the cardia, the mucosa of the esophagus transitions into gastric mucosa. The cardia is also the site of the lower esophageal sphincter (LES) (also termed cardiac sphincter, gastroesophageal sphincter, and esophageal sphincter).
What else can I help you with?
Is there a cardiac region of the stomach?
There are two parts to a stomach: the pyloric section (lower) and the cardiac section (upper). The cardiac section is the place where most of the carbohydrate digestion occurs and it's right after the esophagus. It can also be called the "cardia."
The esophagus and trachea are both open to the?
The esophagus and trachea open into the throat and mouth.
What connects the esophagus and duodenum?
The connection between the esophagus and duodenum is through the stomach, specifically the lower esophageal sphincter and the pyloric sphincter. Food travels from the esophagus to the stomach through the lower esophageal sphincter and then from the stomach to the duodenum through the pyloric sphincter.
What is the flap in your esophagus called?
The name of the structure at the top of the esophagus is the "epiglottis". This structure is very important in protecting the vocal cords, trachea, and the lungs. It does this by covering the opening to the vocal cords and making an airtight seal. It also holds air in our lungs so we can form a cough, and produce extra pressure in our lungs, called "peep" (positive end expiratory pressure). So, it is actually a very important organ.
How does food travel through the esophagus?
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.
What is the ring called at the end of the esophagus?
The ring at the end of the esophagus is the lower esophageal sphincter.
The esophagus connects the pharynx with which organ?
The esophagus connects the pharynx with the stomach. It serves as a muscular tube that carries food and liquids from the mouth to the stomach for digestion. The lower esophageal sphincter, a muscular valve at the end of the esophagus, prevents stomach contents from flowing back up into the esophagus.
What is the lower end of the esophagus termed?
The end bit of the esophagus is the stomach. But before the stomach there's the gastroesophageal junction which leads into the stomach. Just above the junction there is the diaphragm (but that isn't attached to the esophagus) .
What organ Carries food and air?
The pharynx, or throat, carries both food an air. At its end, air goes into the trachea and food into the esophagus.
Food enters the stomach by passing through a muscular structure at the end of the esophagus called?
The cardiac sphincter.
Is there a cardiac region of the stomach?

The esophagus and trachea are both open to the?
The esophagus and trachea open into the throat and mouth.
Do animal have esophagus's?
All mammals and reptiles have an esophagus. The esophagus extends from the end of the windpipe to the stomach and is part of the digestive system.
What connects the esophagus and duodenum?
The connection between the esophagus and duodenum is through the stomach, specifically the lower esophageal sphincter and the pyloric sphincter. Food travels from the esophagus to the stomach through the lower esophageal sphincter and then from the stomach to the duodenum through the pyloric sphincter.

How does the esophagus work?
The esophagus is a muscular tube that connects the throat to the stomach. When you swallow, muscles in the esophagus contract to push food down towards the stomach through a series of coordinated muscle movements called peristalsis. The esophageal sphincter at the lower end of the esophagus opens to allow food to enter the stomach and then closes to prevent backflow.
What instrument is used to view the stomach and esophagus?
An endoscope is used to view the stomach and esophagus through a procedure called an endoscopy. It is a flexible tube with a light and camera on the end that is inserted through the mouth and into the digestive tract to provide internal images for diagnosis and treatment.
