4 major steps of EXTERNAL RESPIRATION.
which are function of pulmonary system? which are of CV system? |
ventilation - gas move from air to alveoli
Diffusion - gas move from alveoli to blood perfusion - gas move thru lung Transport - lung to tissue (only one that is of CV system) |
|

VC? normal value?
|
Vital capacity - maximum a person can expel after lungs completely filled - 4600 mL
|
|
|
what 2 values does VC relate to?

|
What is Respiratory minute volume (RMV) equal to?
|
Vt x resp rate
|
|
|
What is Va? how does it relate to RMV?
|
it is the value of what actually goes into lungs
= (Vt -ADS) x Resp Rate |
