resistance, velocity and flow - got2study2pass

hi guys, if resistance= 1/r^4 then, since the radius of the aorta is biggest, it shud have less resistance, but it does not. Why so


also velocity = 1/cross sect area, so im guesssing velocity in the aorta wud be most right.

As resistance is inversely proportional to 4rth power of the radius,but remember

that aorta has the smallest crossectional area cuz it a single vessel whereas cappillaries

when summed together have the largest crossectional area,so therefore according to the

formula resis is inversely prop to 4rth power of the radius so the aorta shud have high

resistance cuz aorta has smallest crossectional area, so therefore aorta has high velocity.
