As a result of the pumping action of the heart, we are able to feel pulsations in our superficial arteries (e.g. the radial pulse). This effect is an example of which of the following?

A: Pascal’s states that pressure applied to an enclosed fluid is transmitted undiminished throughout the fluid. The LV pushes blood into the aorta at pressure. This pressure distends the artery walls of the brachial artery – even though it is 70 cm away from the heart – and we can feel the pulsations as pressure rises and falls.
