Venturi effect.

Venturi effect.

One of the most important contexts for Fluid Mechanics reasoning for future doctors is the human circulatory system. However, Bernoulli's Law can only be applied in very special and localized circumstances in the cardiovascular system because blood is not an ideal fluid, and the cardiovascular system is not closed.

However one very useful application of Bernoulli's Law in the interpretation of blood flow is to describe a localized pressure decrease produced by high flow rate near blockages. Remember, Bernoulli's Law tells us that if the flow rate is high in a localized area, the pressure will be low there.
