BT_PO 1.47 Discuss the control of blood pressure and the distribution of blood volume and flow throughout the cardiovascular system including:

· The factors determining systemic blood pressure and its regulation and control

· Total peripheral resistance and factors affecting it

· The relationship between organ blood flow and demand and the role of autoregulation

· Clinically significant features of the coronary, cerebral, skin, muscle, renal, hepatic and splanchnic circulations

· The essential features of the microcirculation including fluid exchange and its control
