Esophagus also called as the oesophagus is the hollow, fibromuscular tube-like structure that connects the throat (pharynx) with the stomach. It measures about 25 centimetres long and runs behind the trachea and heart, through the diaphragm and o the uppermost region of the stomach. The oesophagus is about 8 inches long, covered by a mucous membrane. It is a part of the digestive system and also called as the food pipe
The trachea is a wide, hollow, cartilaginous and tube-like structure located in the neck. It is a part of the respiratory system that connects the larynx (voice box )and larynx to the bronchi of the lungs. The trachea is also known as the windpipe and its length ranges between 10 to 11 cm.
The key difference between Esophagus and Trachea is their function. Let us learn more about their differences.

Important Questions on Esophagus And Trachea
- How are oesophagus and trachea separated?
The epiglottis, a flap in the throat separates both the oesophagus and trachea.
- Where does the trachea divide?
The trachea also called the windpipe divides at the carina into two main or primary bronchi – the left and the right bronchus.
- Can an individual live without the trachea?
No. An individual cannot live without the trachea. Because it is an important structure within our respiratory system and is involved in the delivering of the oxygen gas into our bloodstream.
