segmental bronchi.
tertiary bronchioles
The main (primary) bronchi. Right and left.
the trachea is air passage tube that allows air to enter your lungs. the bronchi are two little tubes that are connected to the end of your trachea and lead to the lungs.
Air is a mixture of gases.When we inhale we reduce pressure in our lungs and thus air is diffused in our lungs.This diffusion takes place inside the lungs and between the bronchities.Here the air passage is the trachea/wind pipe.
it goes to ur nasal cavity then go to your larnx to the trachea to the bronchi and air sacs to the lungs :)
Foreign objects that enter the respiratory passageways are more likely to become lodged in the right primary (main) bronchus.
The new cells enter into interphase.

Two air passages which allow air to enter the body are the cilia and aveoli !!!
Primary brochi first enter the lungs on both the left and right sides.
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.
Perhaps you mean the hilum? It is the opening of the lung where the main bronchi (airway) enter the lung together with blood vessels, lymph vessels and nerves.
