Homeostasis, Feedback Loops, and Body Systems

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment in the body, often incorporating feedback regulation.

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, such as regulating body temperature.

Front

What is a positive feedback loop?

Back

A positive feedback loop is a process that amplifies a change in a system, leading to an even greater change, such as during childbirth.

Front

How do the cardiovascular and respiratory systems work together?

Back

The cardiovascular system transports oxygen around the body while the respiratory system brings oxygen into the body.

Front

What role do chloroplasts play in plants?

Back

Chloroplasts convert light energy into chemical energy through the process of photosynthesis.

Front

What is the stimulus in a biological context?

Back

A stimulus is the cause or trigger that leads to a response in an organism.

Front

What is the role of feedback regulation in homeostasis?

Back

Feedback regulation helps to maintain homeostasis by adjusting physiological processes in response to changes in the internal environment.

Front

What is the function of mitochondria?

Back

Mitochondria are the powerhouses of the cell, converting nutrients into energy through cellular respiration.

Front

What is the difference between internal and external environments in homeostasis?

Back

The internal environment refers to the conditions within the body, while the external environment refers to the conditions outside the body.

Front

What is an example of a physiological response to maintain homeostasis?

Back

Sweating to cool down the body is an example of a physiological response to maintain homeostasis.
