← Human Body & HealthIf a patient experiences severe blood loss leading to hypovolemic shock, which consequence follows regarding systemic vascular resistance?
A)Resistance decreases due vasodilation
B)Resistance increases due vasoconstriction✓
C)Resistance remains constant initially
D)Resistance oscillates unpredictably
💡 Explanation
Systemic vascular resistance increases because, in hypovolemic shock, the body initiates vasoconstriction to maintain blood pressure and perfusion of vital organs. Therefore, resistance increases rather than oscillating or remaining constant, as this response prioritizes blood flow to essential areas.
