Respiratory System Deck (P2) Flashcards
What are the 4 major functions of the respiratory system (HINT: OCOA - “Same Love” melody)?
1) Supply oxygen
2) Remove carbon dioxide
3) House olfactory organs
4) Provide air pressure for sound production
Protrusions in the walls of the nasal cavity
What are conchae?
Air passages in the nasal cavity
What are meatuses?
The pharynx is the passageway for either of these 2 things
What is food or air?
What are the 3 sections of the pharynx?
1) Nasopharynx
2) Oropharynx
3) Laryngopharynx
The anatomy term for the voice box.
What is the larynx?
The larynx houses the { } cords.
Vocal
What is the general function of the larynx?
To protect the lower airways from food
Tubes that carry air to the lungs.
What are bronchi?
Why are there more lobes on the right lung than on the left?
To make room for the heart
Gas exchange takes place between the { } and the { }.
1) Alveoli
2) Capillaries
What is the mechanism for which gas exchange occurs?
Diffusion
What is the relationship between the diaphragm, thoracic volume, and thoracic pressure when inhaling?
Diaphragm lowers
Thoracic cavity volume increases
Thoracic cavity pressure decreases
The amount of air entering/exiting the lungs during normal breathing
What is tidal volume?
The volume of air forcibly expelled following normal exhalation
What is expiratory reserve volume?
The volume of air forcibly inhaled following normal inhalation
What is inspiratory reserve volume?
The maximum volume of air that can be exhaled following a deep inhalation
What is vital capacity?
The volume of air left in the lungs even after forcibly exhaling
What is residual volume?
