Thanks to the Doppler effect we can calculate the velocity at which blood is moving through the aorta. Once the average velocity over multiple heartbeats is known (cm/sec), what other parameter is required to calculate the cardiac output (cm3 · sec-1)? a) The volume of the left atrium (cm³) b) The length of the aorta (cm) c) The volume of the left ventricle (cm³) d) The cross-sectional area of the aorta (cm2)
