Alveoli
Bronchi
Lobes
Trachea
The lungs are located in which part of the body?
Abdomen
Thoracic cavity

Cranial cavity
What is the function of mucus in the respiratory system?
To facilitate gas exchange
To trap dust and microorganisms
To help in sound production
To provide oxygen to the blood
When you breathe out, the diaphragm:
Contracts
Expands
Relaxes
