Answer:
Jasmine's body responds with a mechanism of heat loss, such as sweating and evaporation, to reduce her internal body temperature and recover homeostasis.
Explanation:
The human is a homeotherm organism, with a constant body temperature that is between 36.5 and 37 °C. To maintain thermal homeostasis uses several mechanisms.
In the case of Jasmine, the raise of the body temperature, with the exercise, to 38°C stimulates sweat production and its body surface becomes moist. With the evaporation of sweat, body temperature normalizes, since this process involves heat loss.
Also, a voluntary mechanism to lower the temperature is to remove the clothes and remain in a cool environment.
