What is panting and how does it keep an animal cool?

Rapidly expelling hot air and drawing in cooler air is known as panting. When the cool air comes in contact with the moist lining of the lungs and throat, it helps the animal reduce its body temperature. You've definitely seen dogs do it—canines sweat through their paws but also pant to cool off more efficiently.

What is the purpose of panting?

Panting is a controlled increase in respiratory frequency accompanied by a decrease in tidal volume, the purpose of which is to increase ventilation of the upper respiratory tract, preserve alveolar ventilation, and thereby elevate evaporative heat loss.

Why do animals pant when hot?

Panting. Panting is another way that many animals cool down. When an animal pants, it evaporates water from internal body structures. Panting expels hot air and brings in cool air.

How does sweating panting cool off an organism?

Evaporation removes heat and can act as a cooling mechanism. For instance, many mammals can activate mechanisms like sweating and panting to increase evaporative cooling in response to high body temperature.
