The method of animal heat dissipation mainly depends on the external environment, and it is difficult to adjust itself.
Dogs, it doesn't have sweat glands, so it often dissipates heat by sticking its tongue out or drooling. Amphibians such as frogs like to make a hole in the ground, which is generally very wet, and some animals will spit out some saliva to keep their bodies moist; Most animals change their time of day due to the hot weather, usually at night, as is the case with animals in the desert.
For example, the rabbit has a pair of long ears, and in the summer, when the blood flow in the ears is smoother, the rabbit will fan the big ears to dissipate the heat in the body. The long-tailed monkey also likes to wag its long tail when it is hot, because it has a special vein in its tail that quickly dissipates the heat generated in the body.
The summer refuge of birds and insects** is their wings. The constant heat will make the ostriches in the desert flap their wings desperately - the ostriche's wings are their struggle against the cold and heat**, the outer fur of the wings is thick, which can block the cold in winter, and the inside is bare, and the wings can be flapped in the summer to relieve the heat.
There are four main ways to dissipate heat: radiation, conduction, convection, and evaporation.
1) Radiation heat dissipation: The heat of the body is dissipated to the surrounding objects with low temperature in the form of heat rays, that is, it is dissipated in the low temperature air, which is called radiation heat dissipation. This is the main way to dissipate heat in a quiet state and is affected by the ambient temperature.
2) Conduction heat dissipation: It is to transmit the heat from the deep part of the body to the surface of the human body in a conductive way, and then transfer it to the clothes and other objects in direct contact with it. Because clothing and other items are poor conductors of heat, heat transfer is extremely slow, and the thermal conductivity of human subcutaneous fat is low, so the heat dissipated through conduction is very small.
3) Convection heat dissipation: This is a special conduction heat dissipation method, which dissipates body heat into the middle of the air with the help of the continuous flow of air.
4) Evaporative heat dissipation: It is a method that can be used when the external temperature is equal to or exceeds the body temperature, and the heat cannot be dissipated with the help of radiation, conduction and convection. Antipyretic drugs have a sweating effect, after the patient sweats, a large amount of body heat can be taken away by the evaporation of sweat water, to achieve the purpose of reducing fever, the phenomenon of sweating fever and body cold is that we can often encounter.
