Study Notes
Regulation of Arterial Pressure
- The baroreceptor reflex is responsible for the fast regulation of arterial pressure.
- The primary function of the renin-angiotensin-aldosterone mechanism is to regulate blood pressure through the control of fluid volume and vascular resistance.
- The formula for mean arterial pressure (MAP) is: MAP = (SBP + 2DBP) / 3, where SBP is systolic blood pressure and DBP is diastolic blood pressure.
- A decrease in arterial pressure triggers the baroreceptor reflex.
- The primary function of nitric oxide in the control of blood flow is to cause vasodilation, which increases blood flow to tissues.
- The renin-angiotensin-aldosterone mechanism is responsible for the slower, hormonally regulated regulation of arterial pressure.
- A decrease in renal perfusion pressure or a decrease in sodium delivery to the distal tubule triggers the release of renin in the renin-angiotensin-aldosterone mechanism.
