There are two simple rules used to determine how many vessels of different sizes
combine to give a single resistance to flow. In a system composed of
differentsized tubes arranged in series (i.e., sequentially, or end-toend), the total
of that system is simply the sum of the individual resistances. Or, R. ...
= XR. individual (7) total For example, if one were to examine the resistance of a
segment of a tapering artery where the proximal 1 cm of length had an R = 1 PRU
, the next 1 ...
