Homeostasis and Feedback Mechanisms

Front

What detects change and sends a message to the control center in homeostasis?

Back

Receptor

Front

What type of feedback occurs when the response enhances the original stimulus, as seen when a cut causes platelets to signal more platelets to stop bleeding?

Back

Positive Feedback Response

Front

What type of feedback occurs when the response reduces the effect of the original stimulus, such as insulin lowering blood sugar levels?

Back

Negative Feedback Loop

Front

What is an example of a negative feedback loop in the human body?

Back

Maintaining body temperature

Front

Which organ produces hormones that help regulate blood glucose levels?

Back

Pancreas

Front

What is the role of the control center in a feedback mechanism?

Back

It processes the information received from receptors and determines the appropriate response.

Front

What is an effector in the context of homeostasis?

Back

An effector is a component that carries out the response to restore balance.

Front

How does a negative feedback loop function in maintaining homeostasis?

Back

It counteracts changes by initiating responses that return the system to its set point.

Front

What is the primary function of insulin in the body?

Back

To lower blood glucose levels by facilitating glucose uptake into cells.

Front

What happens during a positive feedback loop?

Back

The output enhances or increases the original stimulus.
