Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is thermoregulation?

Back

Thermoregulation is the process of maintaining an internal temperature within a tolerable range, which is crucial for the proper functioning of the body.

Front

What happens when the environment gets cold?

Back

When the environment gets cold, the body may shiver to generate heat and increase body temperature.

Front

What is shivering?

Back

Shivering is the involuntary contraction of muscles to generate heat and warm up the body.

Front

What is a negative feedback loop?

Back

A negative feedback loop is a process that counteracts changes in the body to maintain homeostasis, such as regulating temperature.

Front

What is an example of a positive feedback loop?

Back

An example of a positive feedback loop is the process of childbirth, where contractions increase until delivery.

Front

What is the role of sweat in homeostasis?

Back

Sweating helps cool the body down when it gets too hot, maintaining a stable internal temperature.

Front

What is vasodilation?

Back

Vasodilation is the widening of blood vessels, which helps to increase blood flow and release heat from the body.

Front

What is vasoconstriction?

Back

Vasoconstriction is the narrowing of blood vessels, which helps to conserve heat in the body when it is cold.

Front

What does it mean to be stable in terms of homeostasis?

Back

Being stable means that the internal conditions of the body remain constant and balanced, despite external changes.
