Flashcards
Site of Blood Pressure Control (& Intrinsic)
Cards in this deck (11)
- 1HeartControl of CO (thought venous return)
- 2KidneyControl of Blood Volume
- 3Kidney (Renal Arterioles)Through the RAAS
- 4Resistance ArteriolesNarrow to increase PVR when necessary
- 5Capacitance VenulesStretch to account for inc. blood flow & balances volume/pressure
- 6Baroreflex (1)Inc Blood Pressure stretches the arterial wall and stimulates the baroreceptor
- 7Baroreflex (2)Baroreceptor stimulates SNS & Increases noradrenaline
- 8Baroreflex (3)Inc Noradrenaline = inc PVR, CO & constriction of capacitance vesicles
- 9Baroreflex ReceptorsAlpha Receptor
- 10(Intrinsic Control) Cardiac Output =Venous Return- so the amount of blood in the heart determines the CO
- 11(Intrinsic Control) Stroke Volume is Proportional ToEnd Diastolic Volume
