What happened to the FEV1 percent as the radius of the airways was decreased?

FEV 1 (%) will decrease as the airway radius is decreased. FEV 1 (%) is the amount of air that can be expelled from the lungs in one second during forced expiration. If the airway becomes smaller, then the resistance to airflow will increase and FEV 1 (%) will become lower.

Why does the forced expiratory volume percentage decrease as the radius of the airways is decreased?
Reducing the radius of the airways will affect the capacity of the lungs to exhale the maximum amount of air
When the diameter of a sphere is decreased by 25 percent by what per cent does its curved surface area decrease?
Surface area, S.A., of a sphere with radius r equals to 4pir2.Since the diameter is decreased by 25%, the radius is also decreased by 25%.That is r - 0.25r = 0.75r.So that S.A. = 4pi(0.75r)2 = 2.25pir2
When the radius is increased does the period of rotation increased or decreased?
Generally decreased.
How did changing the radius effect FEV1?
Decreased the FEV1 %
The radius of a cirle is what percent of the diameter?
the radius of a cirle is what percent of the diameter
What happens to resistance if radius of a wire is decreased by a factor of 3?
resistance is inversily proportional to squaire of radius of wire.
If the radius of a circle decreased would the area decrease?
Yes. The area is proportional to the square of the radius. If the radius becomes smaller, so does the area.
Mercury's radius is what percent of Jupiter's radius?
Mercury's radius is 0.3825 that of Earth Jupiter's radius is 11.209 that of Earth So: (0.3825/11.209)*100 = 3.41 percent.
What is the radius if the size factor is fifty percent of a circle?
radius is 2
What percentage of diameter of a circle is the radius?
50 percent of diameter of a circle is the radius.
When surfactant is added what happens to the tidal volume?
FEV1 percentage decreases as the radius of the airway is decreased.
If a radius of a circle is increased by 10 percent by what percent does its area increase?
area goes as radius squared 1.1 x 1.1 = 1.21 or 21%
