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 a receptor in the context of homeostasis?

Back

A receptor is a body part that senses changes in the internal or external environment.

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 an effector?

Back

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

Front

What is a negative feedback loop?

Back

A negative feedback loop is a mechanism that counteracts a change in a physiological variable to maintain homeostasis.

Front

What is an initiation event?

Back

An initiation event is a change that disrupts homeostasis and triggers a response in the feedback loop.

Front

What is a stimulus?

Back

A stimulus is a change inside the organism caused by an initiation event that needs to be addressed.

Front

How does sweating help maintain body temperature?

Back

Sweating cools the body down when temperature rises, helping to restore homeostasis.

Front

What is the role of the hypothalamus in temperature regulation?

Back

The hypothalamus acts as the control center that detects temperature changes and initiates responses like sweating.

Front

What happens during a positive feedback loop?

Back

In a positive feedback loop, a change in a physiological variable leads to an even greater change, moving away from homeostasis.
