Inside each of your lungs there are tubes called bronchi. These branch into even smaller tubes much like the branches of a tree. What are at the ends of these tubes?
A
alveoli
B
diaphragms
C
cells
D
lobus
Explanation: 

Detailed explanation-1: -In your lungs, the main airways, called bronchi, branch off into smaller and smaller passageways. The smallest airways, called bronchioles, lead to tiny air sacs called alveoli.

Detailed explanation-2: -The bronchi are the two large tubes that carry air from your windpipe to your lungs. You have a left and right main bronchus in each lung. After the main bronchi, these tubes branch out into segments that look like tree branches. Many respiratory conditions, such as asthma or bronchitis, can affect your bronchi.

Detailed explanation-3: -Together, the trachea and the two primary bronchi are referred to as the bronchial tree. At the end of the bronchial tree lie the alveolar ducts, the alveolar sacs, and the alveoli. The tubes that make up the bronchial tree perform the same function as the trachea: they distribute air to the lungs.
