Homeostasis and Feedback Review

Front

What are organs?

Back

Organs are structures made up of groups of tissues that work together to perform specific functions in the body, such as the brain, heart, kidneys, and lungs.

Front

What are tissues?

Back

Tissues are groups of cells that have similar functions. Examples include nervous tissue, epithelial tissue, muscle tissue, and connective tissue.

Front

What is the circulatory system?

Back

The circulatory system is a transport system in the body that carries oxygen, carbon dioxide, and wastes to and from cells using the heart and blood.

Front

What are the components of a feedback loop?

Back

All feedback loops consist of a stimulus, an effector, and a response.

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 the role of the heart in the circulatory system?

Back

The heart pumps blood throughout the body, facilitating the transport of oxygen, nutrients, and waste products.

Front

What is the function of the kidneys?

Back

The kidneys filter waste products from the blood and regulate fluid balance, electrolytes, and blood pressure.

Front

What is the difference between positive and negative feedback?

Back

Positive feedback amplifies a response or process, while negative feedback reduces or counteracts a response to maintain homeostasis.

Front

What is an example of a positive feedback mechanism?

Back

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

Front

What is an example of a negative feedback mechanism?

Back

An example of negative feedback is the regulation of body temperature; when the body temperature rises, mechanisms are activated to cool it down.
