Making Connections and Feedback Loops

Front

What is a negative feedback loop?

Back

A process that helps correct an imbalance in the opposite direction, maintaining homeostasis.

Front

What happens when glucose levels are too high?

Back

The body releases insulin to lower glucose levels.

Front

Define homeostasis.

Back

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

Front

Which body systems are involved in regulating pulse rate during exercise?

Back

The respiratory and circulatory systems.

Front

How does physical activity affect pulse rate?

Back

Higher intensity activities, like running, result in a higher pulse rate.

Front

What is the role of insulin in the body?

Back

Insulin helps lower blood glucose levels by facilitating its uptake into cells.

Front

What is the significance of feedback loops in biological systems?

Back

They help maintain homeostasis by regulating physiological processes.

Front

What is the difference between positive and negative feedback loops?

Back

Negative feedback loops counteract changes, while positive feedback loops amplify changes.

Front

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

Back

The regulation of body temperature: when body temperature rises, mechanisms are activated to cool it down.

Front

What is the relationship between exercise intensity and heart rate?

Back

As exercise intensity increases, heart rate also increases to supply more oxygen to muscles.
