Surrounding each lung completely and lining the chest wall
Why do we breathe?
To bring in oxygen and take out carbon dioxide for the purpose of supporting cellular respiration
A word meaning to breathe that isn't inhale/exhale (hint: starts with an "R")

How does air pass through the respiratory system (in order) starting with the nose and mouth
Nose/mouth --> pharynx --> larynx --> trachea --> bronchi --> bronchioles --> alveoli
How can we keep our lungs healthy?
Exercise and avoiding harmful substances- smoking, vaping, environmental toxins
What are the products of cellular respiration?
ATP, carbon dioxide, and water
