What is the last structure of the air passageway in your lungs
Rasek [7]

Answer:

Bronchioles

Explanation:

You inhale through your nose and the air is filtered. It goes down the pharynx. It goes through the larynx. A "door" called the epiglottis opens during breathing. Then it enters the trachea. (windpipe) It goes through the bronchus. The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air. Air ends its pathway in the ________. (I bet you can guess because you're so smart!) They're surrounded by capillaries that connect the pulmonary arteries and veins. This enables the transfer of oxygen and carbon dioxide.

I hope this helped!!! Good luck on the test/quiz/project/homework/etc. you're working on! If you want I can give you a l!nk to the article I used. If not, it's fine too. Have a great day!
