Ventricle (heart) heart pumping volume is ~5 liters/min, resting. Maximum capacity pumping volume extends from ~25 liters/min for non-athletes to as high as ~45 liters/min for Olympic level athletes. In cardiology, the performance of the ventricles are measured with several volumetric parameters, including end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV) and ejection fraction (E). Ventricular pressure is a measure of blood pressure within the ventricles of the heart. During most of the cardiac cycle, ventricular pressure is less than the pressure in the aorta, but during systole, the ventricular pressure rapidly increases, and the two pressures become equal to each
How Many Birds gets faster. The singer states that he's lonely without his girl and doesn't know what to do. The Kids covered the song the same year, lead vocalist Michael Griffith and Tony Borg singing to the Bee Gees backing tracks.
