Question

Each lung is fed oxygen by a separate bronchus. Please select the best answer from the choices provided. T F

Answer 1

Yes it is absolutely true that each lung is fed oxygen by a separate bronchus. There are actually two lungs and two bronchi. Each of the two lungs are safeguarded by the two ribcages as they are placed within the rib cages. The lungs actually consists of elastic sacs that contract and expand for taking in and releasing air. This way oxygen is passed into the blood and carbon dioxide is taken out from the blood and passed out. This is also the main function of the lungs.

Answer 2

Answer:

The given statement is true.

At lungs level, trachea segmented into two primary bronchi: left primary bronchus which enters the left lung and right primary bronchus which enters the right lung.

In each lung, primary bronchi (both left and right) segmented into tertiary bronchi via secondary bronchi.

Tertiary bronchi divide to form smaller airways termed as bronchioles.

These bronchioles eventually connect with alveoli, specialized sac-like structures which form the site for gas exchange.

Thus, we can conclude that each lung is fed oxygen by a separate bronchus.
