Heart | Control of CO (thought venous return) |
Kidney | Control of Blood Volume |
Kidney (Renal Arterioles) | Through the RAAS |
Resistance Arterioles | Narrow to increase PVR when necessary |
Capacitance Venules | Stretch to account for inc. blood flow & balances volume/pressure |
Baroreflex (1) | Inc Blood Pressure stretches the arterial wall and stimulates the baroreceptor |
Baroreflex (2) | Baroreceptor stimulates SNS & Increases noradrenaline |
Baroreflex (3) | Inc Noradrenaline = inc PVR, CO & constriction of capacitance vesicles |
Baroreflex Receptors | Alpha Receptor |
(Intrinsic Control) Cardiac Output = | Venous Return- so the amount of blood in the heart determines the CO |
(Intrinsic Control) Stroke Volume is Proportional To | End Diastolic Volume |
