Question

Explain how the patient’s body tries to increase their blood pressure via the baroreceptor reflex. Draw the baroreptor reflex. Then use arrows to designate increases or decreases on the relationships below.

EDV minus ESV equals SV

SV multiplied by HR equals CO

CO multiplied by TPR equals BP

Answer 1

The baroreceptors (pressure receptors) helps short term control of blood pressure by increasing or decreasing the activity of the heart and by vasodilation and vasoconstriction through the sympathetic and parasympathetic nerves arisen from the cardiovascular center.

Here,

EDV means End Diastolic Volume

ESV means End Systolic Volume

SV means Stroke Volume

CO means Cardiac Output

TPR means Total peripheral Resistance

HR means Heart Rate

BP means Blood Pressure
