Question
The bronchi divide into smaller tubes known as the _______________.Question 19Answera.bronchib.bronchiolesc.trachead.alveoli
Solution
The bronchi divide into smaller tubes known as the bronchioles.
Here's a step-by-step explanation:
-
The respiratory system is responsible for taking in oxygen and expelling carbon dioxide. The process of breathing starts when we inhale air through our nose or mouth.
-
The air then travels down the trachea, or windpipe.
-
The trachea divides into two tubes called bronchi (one bronchus for each lung).
-
Each bronchus then divides into smaller tubes called bronchioles.
-
The bronchioles further divide and eventually lead to tiny air sacs called alveoli, where the exchange of oxygen and carbon dioxide takes place.
So, the correct answer is b. bronchioles.
