blank blood flow to the surface results in greater heat loss

Reduced blood flow to the surface results in greater heat loss. When blood vessels constrict (a process known as vasoconstriction), less warm blood reaches the surface of the skin, which helps to retain body heat. Conversely, increased blood flow to the surface (vasodilation) allows more heat to escape, leading to greater heat loss from the body. This mechanism is part of the body's thermoregulation process, helping to maintain a stable internal temperature.
