The respiratory system is driven lungs
primarily by the
Upper respiratory system structures 1. Pharynx
-Nasophrynx
-Oropharynx
2. Larynx
Lower respiratory system structures 1. Trachea
2. Bronchi
3. Bronchioles
4. Alveoli
Where do the vocal cords lie Larynx
Job of pharynx Warm, filters, and humidifies that air taken in
through the nose and mouth
Where does actual gas exchange Alveoli of the lungs
occur
, Why is it so important to keep alveoli They can get sticky and collapse on themseleves
open (like deflated baloons)
Lungs consist of 1. Right Lung
2. Left lung
Lobes of right lung 3 (superior, middle, inferior)
Lobes of left lung 2 (superior and inferior)
Why does the left lung only have 2 Needs room for the heart
lobes
Lungs are responsible for 1. Bronchoconstriction
2. Bronchodilation
Bronchoconstriction tightening of the bronchus due to the contraction
of the smooth muscle
Bronchodilation Expansion of the airway in the bronchus
To enable the lungs to expand and pleural cavity
contract smoothly, pleural fluid is
produced in the space known as the
Air moves in and out of the lungs inhalation and exhalation
through
Diaphragm muscle that separates the chest cavity from the
abdominal cavity
Surfactant a lubricant made within the lungs → keeps alveoli
