← Human Body & HealthIf a patient experiences severe septic shock leading to widespread vasodilation and capillary leakage, which consequence follows within the cardiovascular system?
A)Increased myocardial contractility maintains output
B)Baroreceptors trigger increased heart rate only
C)Selective vasoconstriction restores organ perfusion
D)Reduced venous return decreases cardiac output✓
💡 Explanation
Septic shock causes systemic vasodilation and increased capillary permeability; because of this, the circulating blood volume decreases due to fluid extravasation. Therefore, reduced venous return to the heart impairs cardiac output, rather than the body compensating effectively with increased contractility or selective vasoconstriction.
