Answer:
Respiration is a type of metabolism.
The respiratory system is a collection of organs involved in carrying out gas exchange in your body. Deep in the lungs, tiny sacs called alveoli take in oxygen from the atmosphere and release carbon dioxide.
Because the lung has two bronchi, it can still function if one bronchus is blocked by a foreign object. No gas exchange will happen to the affected side, and the other lung will compensate for the loss of air. The blocked portion though can become inflamed and can lead to infection and damage.
