What is respiration?
How an organism makes energy
Which structure is more commonly called the voice box?
The larynx
Where would we want the pressure of oxygen to be higher?
The lungs
What percentage of oxygen does your hemoglobin actually release?
25%
What is the function of the rings of cartilage along the length of the trachea?
Structural support; keeps it from collapsing.
What gases are exchanged in the respiratory system? ALSO, which one is a byproduct?
CO2 and O2. CO2 is the byproduct.
What structure defines the split of the trachea into the L and R primary bronchi?
The carina
Where would we want the concentration of CO2 to be higher?
The blood
What is the glottis?
The open space between the vocal cords.

What does surfactant do for the respiratory system?
It keeps the alveoli from collapsing from too much moisture so that gas exchange can continue to happen.
Who are you all going to miss the most when you graduate high school.
In internal respiration, gases are exchanged between what 2 locations?
Blood and body tissues
Organize these structures based on size starting with the largest structure: alveolar ducts, bronchioles, alveoli, main bronchi, and alveolar sacs.
Main bronchi, bronchioles, alveolar ducts, alveolar sacs, alveoli
How does most CO2 travel through the blood?
It is converted into bicarbonate ions.
Explain how we get hiccups and why they make a sound.
Hiccups are triggered by a spasm of the diaphragm which causes us to inhale air unexpectedly. Therefore, the glottis is closed when we inhale the air which makes the hiccup sound.
Explain how we can make sound.
When speaking, we keep the glottis closed. We can then force air through the glottis which vibrates the vocal cords and produces speech.
