mean arterial pressure is a product of  heart rate and cardiac output none of the abouve cardiac output and total peripheral resistance stroke volume and heart rate

Which of the following changes to blood flow is expected to occur as a result of dynamic exercise? Group of answer choices An increase in cardiac output of up to 5X normal An increase in the percent of blood flow to the skeletal muscle compared to at rest All of these occur An increase in ejection fraction

Which of the following would increase flow? Vasoconstriction of the artery An increase in blood viscosity An increase in resistance An increase in stroke volume

Cardiomyopathy results in a thickened, hyperkinetic ventricular  heart muscle Hypertrophic Dilated Restrictive Obstructive

How could the cardiovascular system maintain constant mean arterial pressure following vasodilation and decreased resistance in peripheral blood vessels? increasing stroke volume or heart rate decreasing stroke volume or heart rate O increasing stroke volume or decreasing heart rate decreasing stroke volume or increasing heart rate

if the ventricle cannot pump out as much blood to lung as is coming in through the vena cava what will happen to venous return to the heart increase/decrease

Long term effect of a large A-V fistula will be  a. decreased blood flowb. increased TPRc. high output failured. high hemoglobin levele. low cardiac output

A 50-year-old man has a body weight of 110Kg, resting heart rate is 90bpm, arterial pressure is 120/70mm hematocrit is 35% and body temperature is normal. His pressure-volume diagram of the left ventricle is shown below.What is his resting cardiac output in ml/minute?

A 50-year-old man has a body weight of 110Kg, resting heart rate is 90bpm, arterial pressure is 120/70mm hematocrit is 35% and body temperature is normal. His pressure-volume diagram of the left ventricle is shown below. What is his ventricular ejection fraction?

The heart cannot increase its contraction strength via recruitment because: Gap junctions allow free movement of ions between cells Cardiac action potentials are prolonged The cardiac muscle cell is in its refractory period O Plenty of calcium ions are released to allow full crossbridging during each contraction Heart muscle is always at optimum length
