Although both have the word "heart" in their name, heartburn and heart disease do not share any commonalities. Heartburn, in fact, is the common term for what physicians have termed gastroesophageal reflux disease (GERD), which occurs when acid moves backwards from the stomach into the esophagus, the tube that connects the mouth to the stomach. It has nothing at all to do with the heart.
Pain in the esophagus is commonly called heartburn. Most people do not realize that the esophagus travels down right behind the heart before it connects to the stomach.
The esophagus is a muscular tube that connects the throat (pharynx) with the stomach. It plays a vital role in swallowing food and liquids and propelling them down into the stomach through a series of coordinated muscle contractions. The esophagus is lined with mucous membrane to protect it from damage by stomach acid. It has a sphincter at both ends - the upper esophageal sphincter near the throat and the lower esophageal sphincter at the entrance to the stomach. Disorders of the esophagus can result in conditions such as GERD, heartburn, and esophageal cancer.

No, the esophagus is a muscular tube that connects the mouth to the stomach, allowing food and liquids to pass through for digestion. The nose connects to the throat through the pharynx, which is a different passage from the esophagus.
Scientifically, drinking while standing lets water hit the lower part of the esophagus strongly, & by time this leads to a dilation and relaxation of the sphincter that connects the esophagus and stomach, which finally leads to a medical condition called "GERD: GastroEsophageal Reflux Disease" in which the acids in the stomach pass backward through the "relaxed" sphincter and start "burning" the acid-intolerant esophagus. This leads to the sensation of heartburn that most of people complain of. And that's why drinking while sitting is much better for you.
No, "esophagus" is a noun. It refers to the muscular tube that connects the throat to the stomach.
