I was wondering why when the blood vessels constricted the speed of the blood decreased?
I thought that since the flow rate has to be the same, the volume of blood that reaches a smaller area from a bigger area will increase in speed and hence decrease in pressure?
Perhaps is this due to the fact that the volume of blood from a bigger area has to go through many smaller areas at once, and therefore the velocity would decrease because the volume of blood has to go through many tunnels at once?
