Alveoli
The windpipe is known as the trachea, and it connects to the two bronchi, which then branch off and eventually reach the alveoli in the lungs.
The tubes that connect the bronchi with the alveoli are the bronchioles.
In the pulmonary system, the Alveoli are the small sacs at the end of the bronchioles which are connected to the bronchus. It is within these sacs that gas exchange occurs.
Air travels to and from the lungs though two branches of the trachea called bronchi (one branch equals bronchus; 2 is bronchi). The bronchi subdivide within the lobes of the lungs into smaller and smaller air vessels called bronchioles or bronchioli (singular), that terminate in alveoli. When the alveoli inflate with inhaled air brought in through the bronchi, oxygen enters into the blood. When air is exhaled through the bronchi, the alveoli deflate to expel carbon dioxide and other waste gases from the blood.
bronchi ,alveoli, or veins
After air passes through the larynx, it enters your windpipe, or trachea. The trachea cleans the air again and channels it into the lungs through two large tubes called bronchi. The bronchi divide into smaller tubes and eventually lead to air sacs called alveoli. It is in the alveoli that oxygen moves into your blood and carbon dioxide moves out.
These are called alveoli.The bronchi (or air passages) continually divide into smaller and smaller bronchi in the lungs, until they become bronchioles. The very smallest of the bronchioles end in a tiny sac or 'balloon' called alveoli.The alveoli are surrounded by a dense network of capillaries which allows the exchange of gases between the lungs and the bloodstream.alveoli
Alveoli, (from Latin alveoli, "little cavities") are an anatomical structure which have the form of hollow cavities. Found in the lung, the pulmonary alveoli are spherical extensions of the respiratory bronchioles (small air passages leading off the windpipe) and are the primary sites of gas exchange with the blood. Alveoli are only found in the lungs of mammals.
Alveoli
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.
The alveoli is found at the end of each Bronchiole and Bronchi. The alveoli gets rid of all the carbon dioxide that is in our lungs.If you need more help just ask another question and I'll be free to answer it.
