Calculation of Compliance for Aorta and Vena Cava:

Recall: C = Change in Volume / Change in Pressure

For Aorta:

3 ml / 300 mmHg = .01 ml / mmHg

or E = 1 / .01 = 100

For Vena Cava (1):

2 ml / 8 mmHg = .25 ml / mmHg

or E = 1 / .25 = 4

For vena Cava (2):

.75 ml / 16 = .047 ml / mmHg

or E = 1 / .047 = 21.3
