To enable the stream of air reach the lungs.
CARINA
The trachea is the big straight tube that brings air to the lungs. The trachea then divides into main stem bronchi, lobar bronchi, segmental bronchi, bronchioles, etc.
10 in your right lung and 8 in your left. A total of 18 bronchi.
The main function of a bark in a woody stem includes an outer protective layer and an inner layer of living phloem which transports food through the stem
There are two primary bronchi which are the first divisions branching off from the trachea to take air into the lungs. The primary bronchi then subdivide into lobar bronchi and then again into tertiary bronchi which continue to divide until they are tiny bronchioles which supply each of the alveoli in the lungs. The left primary bronchus leads to the left lung and the right primary bronchus leads into the right lung. The bronchi contain rings of hyaline cartilage which help to provide flexible support to the airways.
The point at which the trachea splits into the right and left mainstem bronchi is called the carina. Hope this helps.
Bronchi
The bronchi are the tubes that actually carry the air to the lungs, they have a different function than the alveoli which function in the process for gas exchange.
The word 'bronchi' is the plural form of the singular noun bronchus.
To transfer food and water back and forth from the leaves and stem. Also to keep the laves aloft to get more sunlight for the process of Photosynthesis.
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.
Cartilage keeps bronchi open
