Hemodynamics

With a stroke volume of ~ 70 ml, and heart rate of 70 bpm, mean aggregate flow throughout the CV system is 80 ml/s. This value doesn't change as the cross sectional area grows from 4 cm2 for the aorta to over 2800 cm2 for the capillaries, which means that velocity in the capillaries decreases quite a lot.

The largest cross sectional area is in the post-capillary venules, however.

Alterations in normal fluid homeostasis results in edema.
