How the body temperature is regulated by the skin
How the skin helps regulate the temperature of mammals
Processes by which the skin help to regulate the body temperature of a mammal
The mammalian skin helps to regulate the body temperature in specific ways. The ways that the temperature of the body of the mammal is regulated can vary from one organism to another.
how The skin helps to regulate the body temperature on hot days, on different weather conditions and environmental factors
On a hot day, when the weather is hot or environment is hot, mammals keep its body temperature constant.
Any rise in the body temperature as a result of rising of Environmental temperatures, stimulates the following Processes to get rid of excess body heat. So on this article I am going to a little about the ways that the skin helps to regulate the body temperature
1. vasodilation process of temperature control of the skin.
The capillaries near the surface of the skin controls the heat loss while those in the deeper layers of the skin constrict. This causes a large volume of blood to flow near the surface of the skin so that heat is lost to someone else via a process called conduction, convection and radiation. The next way in which the skin helps to regulate the body temperature is called sweating
2. Regulating body temperature through sweating.
In humans, the sweat glands active and produce large amount of sweats the flow out onto the surface of the skin causing the temperature inside to go down.
Well, as the sweat evaporates, heat from the body is used up thus cooling the body takes place
3. The skin regulates the body temperature by decreasing metabolic rate.
The body can slow down it's activities to reduce the metabolic rate and this is caused by the skin.
The reduction of the metabolic rate in the body through the help of the skin reduces the heat released by metabolic reactions.
This process is like a driver who runs up his car at 150 km per hour versus another driver Who rump up his car 60 kilometres per hour for the same distance as the 150 kilometre-per-hour.
It is natural that the temperature produced by the engine running 150 kilometres per hour will be hotter even when same distance will be covered
4. How lowering of the hairs through skin regulate temperature on the body
In any animal that is hairy, the hair erector muscles relaxes causing the hair to lie flat on the skin surface. This forces out most of the air trapped among the hairs.
without this insulating layer, the animal loses more heat from the body
How the skin regulates the body temperature on a cold day and on a cold weather
On a cold day, a mammal is able to keep its body temperature constant. How does the mammals regulate the body temperature in this way? A fall in body temperature is a result of a fall in environmental temperature which stimulates the following processes to produce and conserve heat.
1. Vasoconstriction process of temperature regulation
In this process the capillaries near the skin surface is constrict while those in the deeper layer dilate.
This process then conserves heat
2. The body of mammals can regulate sweating in cold weather
In humans the sweat gland become inactive and produced very little sweat that flows out to the skin surface
As a result, heat loss through evaporation of sweat is drastically reduced thereby conserving body heat
3. How the skin regulates the body temperature through increasing metabolic rate in cold weather.
How the body temperature increases metabolic rate, especially that of the liver in order to produce more heat.
Shivering of the body is also aimed at increasing the metabolic rate of the body.
Physical activities like running help to produce heat in cold weather
