- Illuminate the Truth Stroke Volume Highlight the correct word in each of the following sentences. 1. (Preload)(Afterload) is the amount of tension, or stretch, in the ventricular muscle just before it contracts. 2. (Contractility)(Stroke volume) is the force with which ventricular ejection occurs. 3. Starling's law of the heart states that the more the ventricle is stretched-within limits-the (less)(more) forcefully it will contract. 4. The force against which the heart must work to eject its volume of blood is called the (cardiac output)(afterload). 5. Factors that affect contractility are called (chronotropic) (inotropic) agents. 6. Factors that affect heart rate are called (diastolic)(chronotropic) agents.arrow_forwardCould you help me with this question?
