Understanding the Circulatory System

Front

What are the four main chambers of the heart?

Back

right atrium, right ventricle, left atrium, left ventricle

Front

What is the function of the left ventricle?

Back

To pump oxygenated blood to the body.

Front

Name the three types of blood vessels.

Back

arteries, veins, capillaries

Front

What is the primary function of arteries?

Back

The primary function of arteries is to transport oxygenated blood from the heart to the body.

Front

How do veins differ from arteries?

Back

Veins carry deoxygenated blood, have thinner walls, and contain valves, while arteries carry oxygenated blood and have thicker walls.

Front

What role do capillaries play in the circulatory system?

Back

Capillaries enable the exchange of substances between blood and tissues.

Front

What is the main function of red blood cells?

Back

To transport oxygen and carbon dioxide.

Front

How do red blood cells transport oxygen?

Back

Red blood cells transport oxygen by binding it to hemoglobin.

Front

What is the significance of hemoglobin in red blood cells?

Back

Hemoglobin is significant for transporting oxygen and carbon dioxide in red blood cells.

Front

Describe the pathway of blood flow through the heart.

Back

The pathway of blood flow through the heart is: body -> right atrium -> right ventricle -> lungs -> left atrium -> left ventricle -> aorta -> body.
