Circulatory, Respiratory & Excretory Review FLASHCARD

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 the normal resting pulse rate for a healthy human?

Back

The normal resting pulse rate for a healthy human is typically between 60 to 100 beats per minute.

Front

What is ATP and its role in the body?

Back

ATP (adenosine triphosphate) is a molecule that stores and transfers energy within cells, essential for various cellular processes.

Front

What is the primary function of the cardiovascular system?

Back

The primary function of the cardiovascular system is to transport gases (oxygen and carbon dioxide), nutrients, hormones, and waste products throughout the body.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are organic molecules?

Back

Organic molecules are compounds primarily made of carbon atoms, often containing hydrogen, oxygen, nitrogen, and other elements, and are essential for life.

Front

What is the role of the respiratory system?

Back

The respiratory system is responsible for the exchange of gases (oxygen and carbon dioxide) between the body and the environment.

Front

What is the significance of maintaining a stable pulse rate?

Back

Maintaining a stable pulse rate is crucial for ensuring that the body receives adequate blood flow and oxygen supply to meet its metabolic needs.

Front

What is active transport in biological systems?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is the function of the kidneys in the excretory system?

Back

The kidneys filter waste products from the blood, regulate fluid balance, and maintain electrolyte levels in the body.
