blood pressure

Might sound basic, but whats the need for a minimum blood pressure of 10.65kPa in the aorta and only 0kPa within the ventricles (a comparative)? Cheers x

So the only thing I can think of is that arteries are highly elastic and will be constantly exerting a force on the blood as the elastic recoils. The ventricles on the other hand do not have this elastic recoil effect. Imagine it like this, if you had a balloon and a small plastic bag, and you filled both with water, the pressure in the balloon will be higher
