Which of these phrases accurately describes Starling's Law? Increased arterial pressure A decreases stroke volume. Increased EDV tends to increase B stroke volume. As heart rate decreases, filling time C and preload both increase. As venous return increases, cardiac D sarcomeres stretch and increase the force of contraction. Sympathetic nervous system stimulation increases the force of ventricular contraction.
