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 an effector in the feedback loop?

Back

An effector is a body part that makes a change to bring the system back to homeostasis.

Front

What role does the control center play in homeostasis?

Back

The control center processes information from receptors and determines the appropriate response to maintain homeostasis.

Front

What is a receptor in the context of homeostasis?

Back

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

Front

What is an initiation event in a negative feedback loop?

Back

An initiation event is the change in the environment that disrupts homeostasis.

Front

What is the role of the hypothalamus in temperature regulation?

Back

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

Front

What happens when body temperature increases during exercise?

Back

The body senses the increase in temperature and activates sweat glands to cool down.

Front

What is the stimulus that restores homeostasis after exercise?

Back

The stimulus that restores homeostasis is the decrease in body temperature.

Front

What is the first step in the feedback loop when homeostasis is disrupted?

Back

The first step is the initiation event, which causes a change in the internal environment.

Front

What is the response in a feedback loop?

Back

The response is the action taken by the effector to counteract the change and restore homeostasis.
