Detailed explanation-1: -The wall of the esophagus consists of four layers: mucosa, submucosa, muscularis propria, and adventitia.
Detailed explanation-2: -The lower esophageal sphincter (LES) is a bundle of muscles at the low end of the esophagus, where it meets the stomach. When the LES is closed, it prevents acid and stomach contents from traveling backwards from the stomach. The LES muscles are not under voluntary control.
Detailed explanation-3: -Smooth muscle, or involuntary muscle, is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, blood vessels, and the arrector pili in the skin, in which it controls the erection of body hair.
Detailed explanation-4: -The esophagus is located in the center of your chest in an area called the mediastinum. It lies behind your windpipe (trachea) and in front of your spine.
