The contraction phase of the cardiac cycle is known as mean arterial pressure diastole systole pulse pressure cardiac output

The first heat sound is caused by contraction of the ventricle closing of the semilunar valves opening of semilunar valves closing of atrioventricular valves Which of the following lists the correct order of blood flow? left ventricle > left atria > aorta > systemic arteries right atria > right ventricle > aorta > pulmonary arteries left ventricle > aorta > systemic arteries > systemic capillaries inferior and superior vena cava > left atrium > left ventricle > aorta Most of the ventricle filling occurs during atrial systole. when the AV valve is closed. during ventricular systole. during atrial diastole. during isovolumetric contraction. When the right ventricle contracts, the _____ valve closes and eventually, the _____ valve is pushed open. bicuspid (mitral); pulmonary semilunar tricuspid; pulmonary semilunar tricuspid; aortic semilunar bicuspid (mitral); aortic semilunar aortic; pulmonary semilunar Systolic blood pressure is recorded: in arteries and is the minimum pressure that is recorded during ventricular relaxation. in arteries and is the maximal pressure that is recorded during ventricular contraction. in veins and is the maximal pressure recorded during atrial contraction. in veins and is the minimum pressure recorded during atrial relaxation. in both arteries and veins and is the maximum pressure recorded during diastole of the heart. Moderate stretch (increased preload) of the ventricle will lead to Increased stroke volume and cardiac output Decreased stroke volume and cardiac output Increased stroke volume and decreased cardiac output Decreased stroke volume and increased cardiac output No change in stroke volume or cardiac output Increasing which of the following would cause the heart to work harder; thus, decreasing stroke volume and cardiac output? afterload preload contractility
