Does anatomy bend to the laws of physics?
Gases are comprised of molecules that are in ___________.
Pressure refers to the ______ of the gas over a ______.
Given surface area
What is the formula for Pressure?
P = force / area
What is Brownian Movement?
That the molecules of gases are in constant movement
What is Boyle's Law?
For a gas at a given temperature, PRESSURE and VOLUME are inversely proportional to each other
When volume goes up, pressure goes down.
What is the formula for Boyle's Law?
P x V = K

What is recoil?
Returning to the resting state
Something stretched wants to relax
Is recoil active or passive?
During Inhalation, what three things happen?
The lungs become larger (more volume)
Lung pressure decreases (Negative pressure)
Air flows inward from the atmosphere
During Exhalation, what three things happen?
The lungs become smaller (less volume)
Lung pressure increases (Positive pressure)
Air flows outward.
During Inhalation ________ and ________.
During Exhalation ________ and ________.
What is Negative Pressure?
When pressure decreases
What is Positive Pressure?
When pressure increases
What are the four components of the Respiratory Pump?
Active forces (muscular)
Passive forces (nonmuscular, recoil, gravity)
Air itself (behavior of gas & pressure, physics)
Air passageways (pulmonary structures)
Do the lungs attach to the ribs? What does this do?
Expanding the ribs expands the lungs
What are the upper seven ribs called? What do they attach to?

What are the 8-10 ribs called? What do they attach to?
They attach to a cartiligous extension than then attaches to sternum
What are the last 2-3 ribs called? Why?
