Homeostasis and Feedback Loops

Front

What is homeostasis?

Back

The process by which organisms maintain a relatively stable internal environment.

Front

What type of feedback loop is characterized by a response that reduces the effect of the initial stimulus?

Back

Negative feedback loop.

Front

What is the control center in most advanced animals?

Back

Brain.

Front

What does the control center do in homeostasis?

Back

Sends a message to the effector.

Front

What direction do water molecules tend to move in relation to solute concentration?

Back

Move to areas of high solute.

Front

What is a positive feedback loop?

Back

A feedback loop that enhances or amplifies changes, leading to an increase in the output.

Front

Give an example of a negative feedback loop in the human body.

Back

Regulation of body temperature.

Front

What role do effectors play in homeostasis?

Back

Effectors carry out responses to restore balance in the internal environment.

Front

What is the role of sensors in homeostasis?

Back

Sensors detect changes in the internal environment and send information to the control center.

Front

How does the brain contribute to homeostasis?

Back

The brain processes information from sensors and coordinates responses to maintain stability.
