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 is lower esophageal ring?
Lower esophageal ring is a condition in which there is a ring of tissue inside the lower part of the esophagus (the tube connecting the throat with the stomach). This tissue causes narrowing and partial blockage of the esophagus.
Where is the lower esophageal sphincter?
at the junction of the esophagus and stomachlower-esophageal-sphincter
What is the physiology of the esophagus?
The esophagus has two sets of sphincters at its upper and lower ends. Each of these muscular rings must contract in an exact sequence for swallowing to proceed normally.
What is erythematous mucosa-stomach?
redness or erosion near the stomach and the end of the esophagus
What two types of smooth muscle surrounds the esophagus?
The body of the esophagus is bounded by physiologic sphincters known as the upper and lower esophageal sphincters. The upper sphincter is composed largely of a muscle that is closely associated with the larynx. When relaxed, as it is during swallowing, this muscle pulls the larynx forward and aids in routing food into the esophagus instead of the larynx. The lower sphincter is simply the muscle that surrounds the esophagus just as it enters the stomach. Both the upper and lower sphincter are closed except during swallowing, which prevents constant entry of air from the oral cavity or reflux of stomach contents.
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 muscle located at the end of the esophagus that guards the stomach opening is the?
The Lower Esophageal Sphincter.
What is the Sphincter muscle at end of digestive tract?
The spincters located in the esophagus are: the upper sphincter at the top and the lower (the cardiac sphincter) at the bottom of the esophagus. They regulate the food passing through the esophagus.
What is a pharyngectomy?
the total or partial surgical removal of the pharynx, the cavity at the back of the mouth that opens into the esophagus at its lower end.
What is the saclike organ at the end of the esophagus called?
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 is lower esophageal ring?
Lower esophageal ring is a condition in which there is a ring of tissue inside the lower part of the esophagus (the tube connecting the throat with the stomach). This tissue causes narrowing and partial blockage of the esophagus.
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.
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 is the main functions of the esophagus?
The esophagus takes the food from the mouth to the stomach. Food moves through the esophagus by peristalsis, which is muscle contractions the pushes the food downward. At the end of the esophagus is the lower esophageal sphincter (LES), which prevents food from re-entering the esophagus after it's reached the stomach.
The muscular door between the esophagus and stomach is called the what?
The valve between the esophagus and the stomach is called the lower esophageal sphincter.
What is the sphincter that guards the entrance of the esophagus into the stomach?
The lower esophageal sphincter guards the entrance of the stomach from the esophagus.
The esophagus and trachea are both open to the?
The esophagus and trachea open into the throat and mouth.
