Is bronchus and lungs the same?

Answer 1

The trachea divides into a right and left main bronchus. Each major bronchus then subdivides into smaller airway passages referred to as bronchi. As the airway passages make their way out to the lung tissue, the passages become smaller and are referred to as bronchioles. Eventually the bronchioles terminate into small collections of air sacs known as alveoli, which is where the actual exchange of CO2 and Oxygen occur.

The above answer is partly correct, The bronchus and bronchi and the same, bronchus is singular and bronchi is plural. The primary (main) bronchi have a left bronchus and right bronchus, they later eventually branch into the bronchiole(s).

Answer 2

No, bronchial spasms are often caused by bronchitis. But, they are NOT the same thing. if you have bronchial spasms you won't be able to breath in deep (you can still breath normal just fine though) without getting into coughing fits.

Answer 3

No. Bronchioles are the tiny branches of the "bronchial tree". There are 2 primary bronchi that branch off and become smaller and smaller (brochioles) and eventually end in the alveoli, the tiny sacs where O2 saturation takes place :)

Answer 4

No. The symptoms of both are the same, but Chronic Bronchitis doesn't go away. C Bronchitis is usually caused by smoking, but not always.

Answer 5

No. Bronchitis is inflammation of the bronchis, the larger tubing... bronchiolitis is inflammation of the bronchioles... the smaller tubing.

Answer 6

No. The bronchi are large tubes that lead into the lungs. The lungs are filled with very tiny air sacs called aveoli.
