← Nature & AnimalsWhich process results when a marine mammal exhibits localized vasodilation during deep dives?
A)Oxygen conservation in critical organs✓
B)Increased buoyancy from nitrogen narcosis control
C)Reduced blood viscosity avoiding clotting
D)Enhanced thermogenesis in peripheral tissues
💡 Explanation
During deep dives, some marine mammals undergo localized vasodilation to selectively deliver oxygen to crucial organs because they exhibit the diving reflex, limiting blood flow. Therefore, oxygen conservation occurs in these organs, rather than increased buoyancy, reduced viscosity or enhanced thermogenesis which involve different requirements.
