Now, the line, the slope of this line designates our value for our C, which is the compliance. So if we bring this over to this side, the C will basically describe our compliance. And the higher the slope is, the greater the value of C compliance is. Now, this is the same exact graph except here we're using our veins. And right away notice that the slope for our artery is much lower than the slope of our vein. Why is that?
