Thermoregulation

Front

What term describes animals like mice that generate metabolic heat to maintain a stable internal temperature?

Back

Endotherms

Front

Which of the following best describes the body temperature characteristic of ectotherms?

Back

Body temperature varies with environmental temperature.

Front

When our bodies overheat, sweating helps us cool down. This is an example of what?

Back

Homeostasis.

Front

What is the effect of vasodilation in hot conditions?

Back

It increases heat loss through the skin.

Front

What is the primary response of the body when it is too hot?

Back

Sweating.

Front

Define thermoregulation.

Back

The process by which animals maintain their body temperature within certain boundaries, even when the surrounding temperature is different.

Front

What is the difference between ectotherms and endotherms?

Back

Ectotherms rely on external environmental heat sources, while endotherms generate their own metabolic heat.

Front

What role does the hypothalamus play in thermoregulation?

Back

The hypothalamus acts as the body's thermostat, regulating temperature by triggering responses like sweating or shivering.

Front

What is vasoconstriction and when does it occur?

Back

Vasoconstriction is the narrowing of blood vessels, which occurs in cold conditions to conserve body heat.

Front

Explain the term 'homeostasis'.

Back

Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in external conditions.
