Which effect occurs when a marine mammal experiences extended exertion in cold water resulting vasodilation?

💡 Explanation

When a marine mammal experiences extended exertion in cold water, vasodilation increases blood flow to peripheral tissues in an attempt to supply enough resources to active areas. Therefore increased convective heat loss to environment results because, rather than conservaton via vasoconstriction and countercurrent mechanisms which reduce heat loss.
