Final answer:
Stroke volume can be increased by decreasing total peripheral resistance, which facilitates the heart's pumping during ventricular ejection and benefits stroke volume by promoting better blood flow.
Step-by-step explanation:
The stroke volume (SV), which is the volume of blood pumped by the heart with each beat, is influenced by several physiological factors. Of the given options, stroke volume can be increased by decreasing total peripheral resistance (C). Decreased resistance allows the heart to pump blood more easily during ventricular ejection. An increased SV can also result from sympathetic stimulation, leading to venoconstriction, which in turns increases the return of blood to the heart (venous return).
Decreasing atrial contractility (E) would reduce the effectiveness of the atrial kick, which usually contributes to the final portion of ventricular filling, therefore negatively impacting SV. Increasing heart rate (D) can increase overall cardiac output, but this doesn't necessarily mean increased SV. Rather, SV and heart rate together influence cardiac output. Regarding (A) and (B), compliance changes in the heart or veins would affect the ability of these structures to stretch and fill, but increasing compliance rather than decreasing it would generally be more beneficial for increasing venous return and thus SV.
