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 the 'response' in the context of homeostasis?

Back

The response is the effect or change that occurs in an organism as a result of a stimulus.

Front

What happens if homeostasis is not maintained?

Back

Failure to maintain homeostasis can lead to a lack of internal balance, difficulty in metabolism, and can ultimately result in death.

Front

What is a stimulus?

Back

A stimulus is any change in the environment that triggers a response in an organism.

Front

What is a Negative Feedback Loop?

Back

A Negative Feedback Loop is a process that counteracts a change in a system, helping to maintain homeostasis, such as the regulation of blood sugar levels.

Front

What are the two types of feedback systems in homeostasis?

Back

The two types of feedback systems are positive feedback and negative feedback.

Front

What is positive feedback?

Back

Positive feedback is a process that amplifies a response or increase in a system, often leading to a greater change.

Front

Give an example of a Negative Feedback Loop in the human body.

Back

An example is the regulation of body temperature: when body temperature rises, mechanisms are activated to cool the body down.

Front

What role do receptors play in homeostasis?

Back

Receptors detect changes in the environment and send signals to the control center to initiate a response.

Front

What is the role of effectors in homeostasis?

Back

Effectors are organs or cells that carry out the response to restore balance in the body.
