Unformatted text preview: KIN 205: Chapter 14, Cardiovascular Physiology:
B.1 Pressure (P), Volume (V), Flow (Q) and Resistance (R):
•Q is proportional to ∆P (DP in Figure);
where ∆P = P1 – P2
•in a system with resistance, such as the
cardiovascular system, pressure drops
along the same direction as the flow.
•Resistance opposes flow:
•(similar to ohm's law V = I·R for
electric currents) ∆P = Q·R
•Q = ∆P / R ...
