How does an animal regulate its body temperature?

Many animals regulate their body temperature through behavior, such as seeking sun or shade or huddling together for warmth. ... Some animals use body insulation and evaporative mechanisms, such as sweating and panting, in body temperature regulation.

How do birds regulate their body temperature?

Birds can also control the temperature of their legs and feet separately from their bodies by constricting blood flow to their extremities, thereby reducing heat loss without risking frostbite. Fat Reserves: Even small birds can build up fat reserves to serve as insulation and extra energy for generating body heat.

How do polar bears regulate body temperature?

Thermoregulation. Body temperature, which is normally 37°C (98.6°F), is maintained through a thick layer of fur, a tough hide, and an insulating fat layer (up to 11 cm or 4.5 in. thick). This excellent insulation keeps a polar bear warm even when air temperatures drop to -37°C (-34°F).

Which of the following regulates the body temperature?

Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.
