Sensible thermoregulation is primarily achieved by which structures?

Explanation:
Sensible thermoregulation relies on evaporative cooling from sweat. The structures responsible are the eccrine sweat glands, which are widely distributed across the skin. When the body's core temperature rises, these glands secrete a watery sweat. As that sweat evaporates from the skin, it removes heat and helps lower body temperature. Hair follicles and their associated muscles mainly affect insulation rather than cooling, sebaceous glands produce oil for skin lubrication, and nails protect digits—none of these drive the cooling effect seen with sweating. So the primary means of sensible cooling is sweat production by the sweat glands.
