After atrial contraction is complete, the atrial pressure begins to fall causing a pressure gradient reversal across the AV valves. This causes the valves to float upward (pre-position) before closure. At this time, the ventricular volumes are maximal, which is termed the end-diastolic volume (EDV).
How do I obtain Underage Working Papers in New York State? I'm 16 years old. I got a job at a movie theater for the summer, but they require Working Papers (something they called a green card) in order for me to work, since I'm under the age of 18.
