Front

What is homeostasis?

Back

Homeostasis is a system's ability to maintain a stable state despite changes in its environment.

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 stability.

Front

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

Back

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

Front

What role does the hypothalamus play in homeostasis?

Back

The hypothalamus regulates various bodily functions, including temperature, hunger, and thirst, to maintain homeostasis.

Front

What happens when homeostasis is disrupted?

Back

When homeostasis is disrupted, it can lead to diseases or disorders as the body struggles to regain balance.

Front

Define 'set point' in the context of homeostasis.

Back

A set point is the ideal value or range that a physiological variable should maintain for optimal functioning.

Front

How does the body respond to high blood sugar levels?

Back

The body releases insulin to lower blood sugar levels back to the set point.

Front

What is the difference between positive and negative feedback loops?

Back

Positive feedback amplifies changes, while negative feedback counteracts changes to maintain stability.

Front

What is an example of a positive feedback loop?

Back

An example is childbirth, where the release of oxytocin increases contractions, leading to more oxytocin release.

Front

How do feedback loops contribute to homeostasis?

Back

Feedback loops help the body detect changes and initiate responses to restore balance.
