Q
What is LaPlace’s Law?
A
It is a measurement of wall tension.
sigma=Pr/n
Pressure increases, tension increases
radium increases, tension increases
wall thickness increases, tension decreases
**if radius decreases, pressure increases…the overall effect is that wall tension increases.

Q
What is the purpose of a hypertrophied ventricle?
A
It helps the heart pump more blood & it reduces wall tension.
