What is a positive feedback loop?

Back

A positive feedback loop is a process that amplifies or increases the stimulus, leading to an even greater response.

What is a negative feedback loop?

Back

A negative feedback loop is a process that counteracts a change by reducing the stimulus, helping to maintain homeostasis.

What is thermoregulation?

Back

Thermoregulation is the ability of an organism to maintain its body temperature within a certain range.

Front

What is the role of sweat in thermoregulation?

Back

Sweating helps cool the body down by evaporating moisture from the skin, which lowers body temperature.

Front

What is the response in a feedback system?

Back

The response is the body's reaction to a change in the internal or external environment.

Front

How does exercise affect body temperature?

Back

Exercise increases body temperature due to increased metabolic activity, prompting the body to initiate cooling mechanisms.

Front

What is an example of a physiological response to increased body temperature?

Back

An example is sweating, which helps to cool the body down.

Front

What is the significance of feedback mechanisms in homeostasis?

Back

Feedback mechanisms are crucial for maintaining homeostasis by regulating physiological processes in response to changes.

What happens during a negative feedback response?

Back

During a negative feedback response, the body detects a change and activates mechanisms to counteract that change, restoring balance.
