Circulatory System Review

Front

What is the function of capillaries in the circulatory system?

Back

Capillaries are the smallest blood vessels where the exchange of gases (oxygen and carbon dioxide) occurs between the blood and body tissues.

Front

Which heart chamber receives oxygen-rich blood from the lungs?

Back

The left atrium receives oxygen-rich blood from the lungs.

Front

What color are arteries typically depicted as, and what does this represent?

Back

Arteries are typically depicted as red, representing oxygen-rich blood.

Front

What are the exceptions to the color coding of arteries and veins?

Back

The exceptions are the pulmonary arteries and veins, where the pulmonary arteries carry oxygen-poor blood and the pulmonary veins carry oxygen-rich blood.

Front

What are the largest veins in the body that return blood to the right atrium?

Back

The vena cavas (superior and inferior) are the largest veins that return blood to the right atrium.

Front

Which chamber of the heart receives oxygen-poor blood from the vena cava?

Back

The right atrium receives oxygen-poor blood from the vena cava.

Front

What is the primary role of the heart in the circulatory system?

Back

The primary role of the heart is to pump blood throughout the body, supplying oxygen and nutrients to tissues and removing waste products.

Front

What is the difference between arteries and veins?

Back

Arteries carry blood away from the heart, usually oxygen-rich, while veins carry blood back to the heart, usually oxygen-poor.

Front

What is the role of the left ventricle in the circulatory system?

Back

The left ventricle pumps oxygen-rich blood into the aorta, distributing it to the rest of the body.

Front

What is the function of the right ventricle?

Back

The right ventricle pumps oxygen-poor blood to the lungs for oxygenation.
