Definition
temperature is constant
volume & pressure are indirectly proportional
V increased/P decreased
or
V decreased/ P increased |
|
|
Term
|
Definition
| as velocity increases, lateral wall pressure decreases |
|
|
Term
|
Definition
describes relationship between gas flow & pressure thru tubes
when applied to the lungs, gas flow thru nonrigid airways
if tube narrows, work is harder

Term
|
Definition
weight of gas dissolving in liquid is proportional to the partial pressure of gas
diffusion based on pressure gradient |
|
|
Term
|
Definition
