Homeostasis, Feedback Loops, and Body Systems

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is a feedback loop?

Back

A feedback loop is a biological mechanism in which a change in a system causes an effect that influences the initial change, helping to maintain homeostasis.

Front

What is the role of the respiratory system?

Back

The respiratory system is responsible for taking in oxygen and expelling carbon dioxide, which is essential for cellular respiration.

Front

What organelle is known as the powerhouse of the cell?

Back

The mitochondria are known as the powerhouse of the cell because they produce energy in the form of ATP through cellular respiration.

Front

What are ectotherms?

Back

Ectotherms are organisms that rely on external environmental conditions to regulate their body temperature.

Front

How do the muscular and skeletal systems work together?

Back

The muscular system allows the body to move, while the skeletal system provides structure and support.

Front

What is negative feedback?

Back

Negative feedback is a process that counteracts a change in a system, helping to return it to its set point, such as regulating body temperature.

Front

What is positive feedback?

Back

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

Front

What is the function of the circulatory system?

Back

The circulatory system transports oxygen, nutrients, hormones, and waste products throughout the body.

Front

What is the role of the nervous system in homeostasis?

Back

The nervous system detects changes in the environment and sends signals to other systems to help maintain homeostasis.
