Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the organism's ability to maintain stable internal conditions despite changes in the external environment.

Front

What is the role of the hypothalamus in homeostasis?

Back

The hypothalamus acts as the control center that senses changes in body temperature and initiates responses to restore homeostasis.

Front

What is a receptor in the context of homeostasis?

Back

A receptor is a body part that senses changes in the internal environment, such as temperature or pH.

Front

What happens to body temperature during exercise?

Back

During exercise, body temperature increases due to metabolic activity.

Front

What is the body's response to an increase in temperature?

Back

The body responds to an increase in temperature by sweating to cool down.

Front

What is an internal stimulus?

Back

An internal stimulus is a change within the body that triggers a response, such as hunger or temperature changes.

Front

What is an example of a response to an internal stimulus?

Back

Eating food is an example of a response to the internal stimulus of hunger.

Front

What is the feedback loop in homeostasis?

Back

The feedback loop is a process that helps maintain homeostasis by detecting changes, processing information, and initiating responses.

Front

What is the difference between a stimulus and a response?

Back

A stimulus is a change in the environment that elicits a reaction, while a response is the action taken by the organism to counteract the stimulus.

Front

How does sweating help maintain homeostasis?

Back

Sweating helps maintain homeostasis by cooling the body down when it becomes overheated.
