Is their formula that describes the compliance of our blood vessels? And the answer is yes. So this is basically a linear equation that describes our compliance where C is the compliance of that given blood vessel. The change in volume is by how much volume it increases. And delta p is basically the change in pressure, the difference in pressure between the inside portion of the blood vessel and the outside portion of our blood vessel. So if we change around this equation and if we bring the delta p to this side we get a linear function, we get delta v is equal to the product of c multiplied by delta p and we can easily plot this equation on the XY plot.
