Answer 2

Answer:

Hey mate, here is your answer.

Explanation:

The esophagus is a hollow, muscular tube that connects the throat to the stomach. It lies behind the trachea (windpipe) and in front of the spine. Inadults, the esophagus is usually between 10 and 13 inches (25 to 33 centimeters [cm]) long and is about ¾ of an inch (2cm) across at its smallest point.

At the opening of the upper esophagus there is a special ring of muscle (called the upper esophageal sphincter) that relaxes to open the esophagus when it senses food or liquid coming toward it.

When you swallow, food and liquids travel through the inside of the esophagus (called the lumen) to reach the stomach.

The lower part of the esophagus that connects to the stomach is called the gastroesophageal (GE) junction. A special ring of muscle near the GE junction, called the lower esophageal sphincter, controls the movement of food from the esophagus into the stomach. Between meals, it closes to keep the stomach’s acid and digestive juices out of the esophagus.
