Phytochemical Laws Flashcards
the volume of a fluid that has been completely “cleared” of a substance
clearance
clearance is a flow rate
- the concentration “in the pipe”
the process by which we move atmospheric air into and out of the alveoli
ventilation
what is alveolar ventilation?
clearance mechanisms in the lungs
what is alveolar ventilation in most people at rest?
4L/min
boyle’s law only applies to
gases
If you increase the volume in a container with a gas in it, the pressure of the gas will
decrease
If you decrease the volume in a container with a gas in it, the pressure of the gas will
increase
leplace’s law
Te = P x r / t
Tension (Te) = the tension that is placed on the walls of a cylindrical/spherical structure
Thickness (t) = the thickness of the wall
Pressure (P) = the the pressure inside of the structure
Radius (r) = the radius of the structure
Tension (Te) increases, does radius increase or decrease?
increases
Tension (Te) increases when pressure increases or decreases
increases
Tension (Te) increases does thickness increase or decrease?
decreases
a pathological increase in the diameter of a blood vessel
Aneurysm
What impact does an increase in the diameter have on the tension/stress across the wall of this unhealthy vessel?
tension will increase
T or F: the bigger the diameter/space the greater the tension across the wall
True
