... peripheral resistance (PR). Because ABP is proportional to both CO and PR we can use a formula to calculate ABP: ABP = CO x PR Since cardiac output is equal to heart rate x stroke volume, an increase in either of these factors would lead to an increase in CO, which would lead to an increase in ABP. Likewise an increase in any of the ... vasomotor control centre from the baroreceptors leads to vasoconstriction of the arterioles, which causes an increase in peripheral resistance. Heart rate is also increased, as well as the power of contraction of the heart (stroke volume); these two fact...
