← Nature & AnimalsWhich physiological effect results when human cutaneous vasodilation is maximized during intense exercise?
A)Eccrine sweat gland stimulation increases significantly✓
B)Core body temperature stabilizes rapidly
C)Muscle oxygen extraction efficiency rises dramatically
D)Blood pH experiences immediate metabolic alkalosis
💡 Explanation
When cutaneous vasodilation is maximized, increased blood flow to skin surface occurs because heat dissipation drives evaporative cooling through eccrine sweat glands, significantly increasing sweat production. Therefore sweat gland stimulation increases rather than core temperature stabilization, muscle oxygen extraction, or alkalosis which depend on independent physiological mechanisms.
