4.1 Cardiovascular: Pressures in the CVS
Overview of the systemic circulation
Mean Systemic Pressure (MSP) = 7mmHg
Pressures in the arterial and venous systems
Systolic and Diastolic Pressures
Mean Arterial Pressure (MAP)
MAP = DP + 1/3(SP - DP) = 95mmHg
Right Artial Pressure (RAP) = 0mmHg
Compliance = (change in volume)/(change in pressure)
Difference in compliance between arteries (high) and veins (low)
Pressure gradient
Role of the heart in generating pressure gradient causing blood to flow
