Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the organism's ability to maintain steady (stable) internal conditions.

Front

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

Back

Eating food when you are hungry.

Front

What do negative feedback loops do?

Back

Negative feedback loops are one way an organism can maintain homeostasis.

Front

What are the steps involved in negative feedback?

Back

The steps are initiation event, stimulus, receptor, control center, effector, and response.

Front

What is the stimulus that restores homeostasis in the scenario of exercising?

Back

The body temperature decreases.

Front

What is a stimulus in the context of homeostasis?

Back

A stimulus is a change in the internal or external environment that triggers a response.

Front

What is the role of the control center in homeostasis?

Back

The control center processes the information from the receptor and determines the appropriate response.

Front

What is an effector in the homeostasis process?

Back

An effector is a part of the body that carries out the response to restore balance.

Front

What is the difference between positive and negative feedback?

Back

Positive feedback amplifies changes, while negative feedback counteracts changes to maintain stability.

Front

How does sweating help maintain homeostasis?

Back

Sweating cools the body down when it overheats, helping to maintain a stable internal temperature.
