No they absorb large amounts of oxygen into the blood.
This is a multicellular exocrine gland. It is also a compound alveolar (or ascinar) type.
The passage way is Bronchi to Bronchioles then alveoli to alveolar ducts and exchange of gasses occurs in alveoli. So Answer is No..bronchi not goes directly to alveoli.
I'm not exactly sure but I do know that cocaine in rare cases is still used in eye surgery today as a topical anesthetic so I don't see why not.
Air enters the body through the nostrils or the mouth, passing down the throat to the larynx, and then to the trachea. The trachea divides into two branches in the chest cavity, the right and left bronchi that enter the lungs. The branches of the bronchi narrow down to tubes called bronchioles of less than 1 mm diameter, and these sub-divide into even narrower tubes called alveolar ducts. Each alveolar duct ends in a grapelike cluster of thin-walled sacs, called alveoli. From 300 million to 400 million alveoli are contained in each lung.
where are the lacrimal ducts are located in
it dissolves oxygen in the fluid and from there it can diffuse to the alveolar cells.It goes right back to evolution where single cells have to absorb oxygen from water.All of our cells systems ae aquatic.
Alveolar ducts and tracts are the site of gas exchange in the lungs.
That sounds like a general description of the LUNGS.The lungs are loaded with pulmonary alveoli: small outpouchings along the walls of the alveolar sacs and alveolar ducts; through them, gas exchange takes place between alveolar gas and pulmonary capillary blood.
Respiratory bronchioles, alveolar ducts, and alveoli.
The respiratory looks like an upside down tree, from the trunk to the branches and to fruit (such as an apple). From largest to smallest, the respiratory system consists of the throat to main bronchi, to bronchioles, to terminal bronchioles, to alveolar ducts, to alveolar sacs (aveoli look like tiny grapes).

Trap air in lungs (act as air pockets 4 gaseous exchange).
