← Human Body & HealthWhich outcome results when systemic vascular resistance increases during heart relaxation?
A)Decreased cardiac output volume
B)Increased diastolic blood pressure✓
C)Enhanced arterial pulse pressure
D)Elevated end-systolic ventricular volume
💡 Explanation
Increased systemic vascular resistance hampers blood outflow during diastole leading to increased pressure referred to as afterload. Therefore diastolic blood pressure increases, because the cardiac muscle requires extreme pressure rather than influencing cardiac volume or output.
