The trachea and oesophagus (or esophagus) are the two tubular structures present in the neck region of the human body. They are located close to each other but completely different in functions. The trachea is the windpipe, whereas the oesophagus is the foodpipe of humans.
Read on to explore the major difference between the trachea and oesophagus.
Oesophagus vs Trachea
The important difference between the oesophagus and trachea are given below:
| Trachea | Oesophagus |
| Definition | |
| It is a membranous, tube-like structure that extends from the larynx to the bronchial tube |
It is part of the alimentary canal that connects the throat and stomach
|
| Length | |
| 10 to 11 cm | 25 cm |
| Function | |
| Made of C-shaped semicircular cartilage |
Produces wave-like motion to move food
|
| Composition | |
| 2 parts | 3 parts |
| Also known as | |
| Windpipe | Food pipe |
| Parts name | |
| Thoracic and cervical part |
Abdominal, thoracic part, and cervical part
|
| Organ system | |
| Respiratory system | Digestive system |
| Connection | |
| Upper airway to lungs | Mouth to stomach |
| Opening is protected by | |
| By epiglottis | By two sphincters |
Oesophagus
Oesophagus, also called esophagus, 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 the uppermost region of the stomach. The oesophagus is about 8 inches long and covered by a mucous membrane. It is a part of the digestive system and is also called the food pipe
Trachea
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.

Important Questions on Oesophagus And Trachea
Frequently Asked Questions
How are the 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 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 delivery of oxygen gas into our bloodstream.
