Question
Please use the word bank below (Terms can be used more than once, or not used at all): Pressure volume lower higher preload afterload The contraction and relaxation of heart chambers results in blood movement because fluids flow from high to low If there is a fixed amount of liquid in a sealed chamber and the of that chamber is decreased (such as in contraction), the pressure in that chamber will increase. The blood will only move if the pressure in the next chamber is than the pressure in the current chamber. Pressure can be reduced in a chamber by relaxing its walls and increasing its Following this logic, hypertension limits blood flow out of the ventricles because the high requires the ventricles to raise their own pressure to extreme levels in order for blood to leave and enter the arteries.
