Stroke volume (mL)

The Windkessel model treats the aorta as an elastic reservoir: each heartbeat pumps blood in, and the artery's compliance stores it and releases it smoothly between beats. Stiffer arteries (low compliance) give sharper, higher pressure swings. Educational tool, not medical advice.

Approx. pressure80 mmHg

Time constant RC1.50 s

Cardiac output4.9 L/min

Governing equation

1.5 \frac{d P}{d t} + \frac{P}{1.0} = Q (t)

Reading this result: With this balance the aorta stores each stroke and releases it gradually, keeping the pulse gentle.
