Q1. Name one (1) way your body can alter systemic vascular resistance (1 marks) and statehow this change would affect blood pressure by referring to the blood pressure equation
Solution
A1. One way the body can alter systemic vascular resistance is through vasoconstriction, which is the narrowing of the blood vessels.
This change affects blood pressure by increasing it. According to the blood pressure equation (BP = CO x SVR, where BP is blood pressure, CO is cardiac output, and SVR is systemic vascular resistance), an increase in systemic vascular resistance (through vasoconstriction) would result in an increase in blood pressure, assuming cardiac output remains constant. This is because blood pressure is directly proportional to systemic vascular resistance.
