This Inuk woman is waiting outside the base camp for the return of the hunters. Thanks to an exceptional capillarity, the Inuit blood regulation preserves a good balance between the heart and the extremities of the body. To maintain the temperature of her body at 98.6°F (37°C) and avoid hypothermia enhanced by immobility, she has carefully covered the areas of her body irrigated by large veins responsible of significant heat losses : her neck along the carotid arteries and the jugular veins, her knees, her wrists and her head.
