Trachea vs. Bronchi — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 21, 2023
The trachea is the main airway leading from the larynx to the lungs, while bronchi are the two primary branches of the trachea that carry air into each lung.

Key Differences
The trachea, commonly referred to as the windpipe, serves as the principal conduit for inhaled air after it passes through the larynx. The bronchi, on the other hand, are extensions of the trachea that split into two main branches, directing air into the right and left lungs.
Structurally, the trachea is a singular tubular structure fortified by C-shaped cartilage rings. In contrast, the bronchi diverge from the trachea and further subdivide into smaller bronchioles within each lung.
Functionally, the trachea acts as the initial passageway for air coming from the nose or mouth on its journey to the lungs. The bronchi, conversely, play a role in distributing this air more specifically to each of the lung's lobes.
The trachea's position is central and anterior in the thoracic cavity, running vertically from the larynx to where it bifurcates, forming the bronchi. The bronchi then branch into the lungs, guiding air into these organs.
Both the trachea and bronchi are lined with mucus-producing cells and cilia. These structures work in tandem to trap and expel foreign particles, ensuring cleaner air reaches the lung's deeper parts.

Compare with Definitions
Trachea
The main airway connecting larynx and lungs.
The trachea is the central airway that connects the throat to the lungs.
Bronchi
Tubes that funnel air into the lungs.
The bronchi distribute inhaled air to the right and left lungs.
Trachea
Lined with mucus-producing cells.
The trachea has cilia and mucus to help filter out contaminants.
Bronchi
Further divide into bronchioles.
The bronchi continue to split, becoming smaller tubes called bronchioles.
Trachea
(Anatomy) A thin-walled, cartilaginous tube descending from the larynx to the bronchi and carrying air to the lungs. Also called windpipe.
Bronchi
Lined with mucus-producing cells.
Like the trachea, the bronchi have cilia to filter and expel contaminants.
Trachea
(Zoology) One of the internal respiratory tubes of insects and some other terrestrial arthropods, which are connected to the spiracles and are used for gas exchange.
Bronchi
Two primary branches of the trachea.
The trachea divides into the bronchi, which lead to each lung.
Trachea
(Botany) A tracheary element.
Bronchi
Primary airway passages to lung lobes.
The bronchi ensure that each lobe of the lung receives air.
Trachea
(anatomy) A thin-walled, cartilaginous tube connecting the larynx to the bronchi.
Bronchi
Plural of bronchus.
Trachea
The xylem vessel.
Bronchi
Inflection of bronchus
Trachea
(entomology) One of the cuticle-lined primary tubes in the respiratory system of an insect, which extend throughout its body.
Bronchi
See Bronchus.
Trachea
The windpipe. See Illust. of Lung.
Trachea
One of the respiratory tubes of insects and arachnids.
Trachea
One of the large cells in woody tissue which have spiral, annular, or other markings, and are connected longitudinally so as to form continuous ducts.
Trachea
Membranous tube with cartilaginous rings that conveys inhaled air from the larynx to the bronchi
Trachea
One of the tubules forming the respiratory system of most insects and many arachnids
Trachea
Tubular structure fortified with cartilage rings.
The C-shaped cartilage rings provide the trachea its shape and rigidity.
Trachea
Principal conduit for inhaled air.
Foreign particles can get lodged in the trachea, causing choking.
Trachea
Known as the windpipe.
If something obstructs the trachea, breathing can become difficult.
Common Curiosities
What is the primary function of the trachea?
The trachea serves as the main airway, directing inhaled air from the larynx to the lungs.
Are there multiple tracheas in the human body?
No, there's only one trachea, often referred to as the windpipe.
Do the bronchi have subdivisions?
Yes, the bronchi further subdivide into smaller tubes called bronchioles.
Can infections affect the trachea?
Yes, infections like tracheitis can inflame the trachea, causing discomfort and breathing difficulties.
What gives the trachea its rigidity?
The trachea is fortified by C-shaped cartilage rings that provide its shape and rigidity.
How many bronchi are there in the human respiratory system?
There are two primary bronchi: one for the right lung and one for the left.
How do bronchi ensure even air distribution?
The bronchi branch out extensively, ensuring that air is distributed to all parts of both lungs.
How does the trachea's size compare to the bronchi?
The trachea is wider than individual bronchi but is similar in diameter to them combined.
Are there any conditions that specifically affect the bronchi?
Yes, bronchitis is an inflammation of the bronchi, often due to infection or other irritants.
How do the bronchi relate to the trachea?
The bronchi are the two main branches that diverge from the trachea, leading air into the right and left lungs.
What is the role of mucus in the trachea?
The mucus in the trachea traps foreign particles, helping to cleanse the air before it reaches the lungs.
Do the bronchi contain cartilage like the trachea?
Yes, the bronchi also have cartilage, but it's more in the form of plates or irregular shapes.
Where does the trachea bifurcate into bronchi?
The trachea bifurcates into the bronchi in the lower part of the neck, just above the chest.
What happens if the bronchi become constricted?
Bronchi constriction can reduce airflow, leading to conditions like asthma or bronchitis.
Can injuries to the trachea be life-threatening?
Yes, since the trachea is the main airway, severe injuries can obstruct breathing and be life-threatening.
