Front 2

If you have more perfusion than ventilation, _______ will occur:

Back 2

Shunting

Front 3

If you have more ventilation than perfusion, ______ is the result

Back 3

Wasted ventilation
(dead space)

Front 4

V/Q ratio by region of the lung:
Apices:
Middle:
Bases:

Back 4

V/Q Ratio:
A- 3.3 (low blood flow)
M- 1.0 (moderate blood flow)
B- 0.66 (high blood flow)

Front 5

Since bloodflow changes considerably from top to bottom in the upright lung, the bases of the lungs
receive ____ x more blood than the ______:

Back 5

Bases receive 20 x more blood and the apices

Front 6

Ventilation is also increased in the lung bases, with approximately ____ x as much ventilation going to the bases than to the _____:

Back 6

4 x more to the base is than the apices

Front 7

Henry's law: a volume of a gas that will dissolve in a liquid is:

Back 7

= to its partial pressure of a gas x it's solubility coefficient

Front 8

Only ____ % of the oxygen in the blood is dissolved in:

Back 8

5% dissolved in
Blood and plasma
