Contracts and flattens
Why does air move into the lungs during inspiration?
The volume of the thorax increases, so the thoracic pressure increases above atmospheric pressure, sucking air in
The volume of the thorax increases, so the thoracic pressure drops below atmospheric pressure, sucking air in
The volume of the thorax decreases, so the thoracic pressure drops below atmospheric pressure, sucking air in
The volume of the thorax decreases, so the thoracic pressure increases above atmospheric pressure, sucking air in

True or false?
In humans, gas exchange only occurs in the alveoli. The rest of the respiratory system just transports air in and out of the alveoli.
True
False

Before inhalation
What do cells use oxygen for?
Making energy from cellular respiration
Burning sugar to produce heat
We combine it with coal to make carbon dioxide
Clearing toxins from the cytoplam
Where does the carbon dioxide that we exhale come from?
As cells in our lungs degrade, they release it
Our cells produce it as a waste product of respiration
