To provide ideal conditions for enzymes to carry out metabolic reaction, otherwise they become denatured and cease to function. Although the temperature around our extremities varies enormously, it is the CORE body temperature that must be kept at a constant 37oC.

Do all organisms have the ability to maintain a constant internal temperature?
Not all organisms have the ability to maintain a constant internal temperature. Cold-blooded organisms like reptiles and amphibians need external sources like the sun to help them maintain a healthy temperature.
What does water help to regulate?
Water's high specific heat capacity helps to maintain body temperature. High specific heat capacity indicates a need for more energy to raise or lower the temperature of water. Sweat is another way that water helps maintain temperature. When sweat evaporates it draws in energy from the surroundings (the air and the body surfaces it is in contact with), effectively lowering the temperature.
Why do you need to maintain your body system?
exersising
Explain how metabolism and homeostasis are related?
Homeostasis is the maintenance of a constant internal environment. In the Biology context, it means a constant body environment, for example, constant body temperature, blood glucose level. Metabolism refers to the reactions that take place in the body which allows life to be maintained. You need to have metabolism taking place in order to maintain homeostasis.
Why mammalian enzymes have optimum temperatures of approximately 40oC whereas plant enzymes have optimum temperatures of 25oC?
Human body temp is constantly maintained at 37 degrees so our enzymes have evolved to work best at this 'warm' temperature . We like nearly all other mammals are warm blooded. Plants do not have to keep their temperature constant and generally exist in colder conditions and can tolerate far greater deviations in temperature hence their enzymes tend to work best at lower temperatures.
What are the adaptations for maintaining a constant body temperature?
The adaptations for maintaining a constant body temperature are depending on the location of the person. Some people may need to layer up and warm up others may need to find ways to cool off and keep their body at a constant temperature.
What is the most expensive zoo animal to feed on a pound-for-pound basis?
Any kind of shrew as they are in serious need to maintain a constant body temperature. Their ratio of surface area to body volume is very small and they radiate away most of their body temperature so they must constantly replace it.
Why does the circulatory system need to regulate a constant body temperature?
helps protect the body against bacteria
Are cows endothermic?
Yes. Elephants maintain a constant body temperature like other mammals. They generate heat from their food. Of course they also need to cool down sometimes as they live in such hot places. This is why they have big ears. Blood circulates through them so it can lose heat to the surroundings.
Why are bees furry?
It helps them maintain body heat. They need a body temperature of at least 75oF (25oC) in order to be able to fly.
Do all organisms have the ability to maintain a constant internal temperature?
Not all organisms have the ability to maintain a constant internal temperature. Cold-blooded organisms like reptiles and amphibians need external sources like the sun to help them maintain a healthy temperature.
How can a cold blooded animal evolve into a warm blooded animal?
Cold blooded animal mean,those animals cannot controle their body temperature.They change body temperature as with the environment.eg-Reptiles,fish etc.Warm blooded animals have a constant core body temperature and are able to controle their body temperature.e-all mammals includinh humans.
Do you need more calorie in summer than in winter?
No, typically you need more calories in winter due to your body maintaining your internal temperature. Because the temperature difference (dT) is smaller in summer, this requires less internal heating to maintain your body temperature.
What does your body need to maintain body temperature?
At 98.6 degrees Fahrenheit.At 37 degrees Celsius It depends on the person, but the average is at 98.6 degrees Fahrenheit.
How can we maintain temperature of a metal at zero degree and 50 degree?
If the metal can be submerged, put it in an ice water bath using pure water to maintain 0 C. To keep it at 50 C, you could use a constant temperature bath. If the metal can not be submerged, you might need a temperature controlled chamber.
Why your body need energy when you walk during cold season?
Energy is used to maintain homeostasis, your body works constantly to keep your body at a normal temperature and pH etc.
Why do people eat less in hot weather?
The job of the metabolism is to keep body temperature up, but when it's already warm the body doesn't need that much energy to maintain the body temperature. In other words, we eat less.
