The smallest is a segmental bronchus.
The trachea is the largest and branches into the main (left and right) bronchi which then branch several times before branching into lobar bronchi and then segmental bronchi.
Each lung is made up of lobes (generally the left lung has 2 lobes and the right has 3) and the lobes are comprised of segments.

What is the route of air from the external nares to alveolus?
Nostrils → Nasal Cavity → Pharynx → Larynx → Trachea → Main Bronchus → Lobar Bronchiole → Segmental Bronchus → Bronchiole → Terminal Bronchiole → Respiratory Bronchiole → Alveolar Duct → Atrium → Alveolus
What are the first branches off the trachea are called?
Primary Bronchus
What is the function f Bronchus?
Allow air to pass from trachea to lungs
What is the function of your primary bronchus?
The right bronchus is a passage leading from the trachea/windpipe into the right lung. When objects are aspirated, they are more likely to end up in the right bronchus than the left because its angle at the carina (the point where the trachea divides into a left and right bronchus) is more vertical/leads more straight down
What organs where associated with respiration?
Nasal cavity,Larynx,Pharynx,Trachea,Bronchus,Bronchioles,Alveolii in Lungs.
Inhaled air passes through which of the following last?
It goes: trachea Mainstem Bronchus lobar bronchus segmental bronchus bronchiole Alveolar duct Aveolus
What is the two tubes that connect to the trachea and to bronchioles called?
Trachea branches to the mainstem bronchus branches to the lobar bronchi branches to the segmental bronchi to the bronchioles branches to the terminal bronchioles branches to the respiratory bronchioles branches to the the alveolar ducts finally lead to the alveoli.Or... Trachea to Bronchus (Bronchi) to the bronchioles to the alveolar ducts to the alveoli.
What is the route of air from the external nares to alveolus?
Nostrils → Nasal Cavity → Pharynx → Larynx → Trachea → Main Bronchus → Lobar Bronchiole → Segmental Bronchus → Bronchiole → Terminal Bronchiole → Respiratory Bronchiole → Alveolar Duct → Atrium → Alveolus
Where does the trachea live in are lungs?
The trachea branches off into the primary bronchus , secondary bronchus etc all the way to the alveoli.The primary bronchus is the first extension of the trachea to enter the lungs.
What are the two branches of the trachea?
The wind pipe is called a trachea. It brings air from your mouth down into your lungs. It is a straight tube at the top that separates into two branches, one going into each lung. These are the left bronchus and right bronchus.
What is meant bronchus?
Bronchus refers to one of the branches (air passages) of trachea that go into the lungs.
What structure receives air after the trachea?
the bronchi
What do you use your trachea for?
The trachea, or windpipe, is a tube that connects the pharynx or larynx to the lungs, allowing the passage of air.
Does the trachea enter the lungs?
According to a figure in my human biology book if the trachea and the Bronchus is made out of the same matter then the Trachea does enter the lung. Unless the bronchus is made out of unique tissue muscle etc.
What are the first branches off the trachea are called?
Primary Bronchus
What are the two branches of windpipe?
The two branches of the trachea (windpipe) are the left bronchus and the right bronchus. The bronchi lead into each lung, and are a part of the respiratory system.
What is primary secondary and tertiary bronchus?
A primary bronchus is the first branch off the trachea, further branching leads to the secondary bronchus and then tertiary as you get deeper into the lung.
