Which of the following is not correct regarding the relationship between pressure, flow, and resistance in the cardiovascular syste? flow (f) is inversely proportional to the pressure gradient (ap) in the blood vessels flow (f) through the entire circulation equals cardiac output (co). the relationship between resistance (r) and flow (f) is the opposite of the relationship between pressure (ap) and flow (f) resistance (r) is more important than the pressure gradient (δρ) in influencing blood flow to an individual organ.
