Cardiac Physiology I I. Cardiac Cycle repeating pattern of contraction and relaxation, that allows the chambers to fill and empty with blood as the chambers fill with blood, this causes the pressure within the chamber to _____________, when they are empty, the pressure ______________ these pressure relationships determine the movement of blood through the heart two phases: systole: diastole: Atrial Systole (a) In the beginning, all 4 chambers are relaxed, and the ventricles are partially filled with blood. As the atria contract, ( __ pressure), this empties all of the blood into the ventricle, topping them off. Atrial Diastole (b) Now, pressure in atria ___, ventricles are full of blood = __________________________ Ventricular pressure is _______________. Ventricular Systole early (c) Ventricles start to contract (just a little), this causes the pressure to rise even faster. Pressure reaches a point where the _____________
