Answer 1

Explanation:

1.

Bronchi are the main passageway into the lungs. The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. ... These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide

2.

bronchus is a passage or airway in the respiratory system that conducts air into the lungs. The first bronchi to branch from the trachea are the right main bronchus and the left main bronchus, also known as the primary bronchi.

3.

a.Bronchi are the main passageway into the lungs. When someone takes a breath through their nose or mouth, the air travels into the larynx. The next step is through the trachea, which carries the air to the left and right bronchus.
