Explain application of bernoulli's principle in lift of aeroplane, spinning ball, heart attack

The lift in the wing is similar to the Bernoulli's equation. The pressure on the one side of the ball makes it to mover faster than the other side. In heart attack As the blood rushes through the constricted artery, the internal pressure  drops and again the artery closes.

Explanation:

The determination of the relation between the pressure, density and velocity at each point of a fluid can be done with Bernoulli's principle.The lift of the aircraft makes it to move forward and upward. This is achieved based on relationship between the angle of the wing and the turbulent flow that helps whether to increase or decrease the lift of the wing. This is similar to the Bernoulli's equation and hence they are associated with each other.  

A ball contains stitches on the middle. While a ball spins the pressure is induced by the ball stitches. This will increase the pressure to decrease one side when compared to the pressure of the other side of the ball. This enables it to move faster.  The pressure must be increased for maintaining a constant rate flow of blood in artery. Heart muscle is very essential factor for increasing this pressure. The person will have heart attach when there is dislodging of the plaque occurs.
