Circulatory System Flashcard

Front

What is the primary function of the circulatory system?

Back

To transport oxygen, nutrients, hormones, and waste products throughout the body.

Front

What are the main components of the circulatory system?

Back

Heart, blood vessels (arteries, veins, capillaries), and blood.

Front

What is the role of arteries in the circulatory system?

Back

Arteries carry oxygenated blood away from the heart to the tissues.

Front

What is the role of veins in the circulatory system?

Back

Veins carry deoxygenated blood back to the heart.

Front

What is the function of capillaries?

Back

Capillaries are small blood vessels where the exchange of oxygen, carbon dioxide, nutrients, and waste occurs between blood and tissues.

Front

What is the heart's structure?

Back

The heart has four chambers: two atria (upper chambers) and two ventricles (lower chambers).

Front

What is the significance of the heart valves?

Back

Heart valves ensure unidirectional blood flow through the heart and prevent backflow.

Front

What is a blood smear and its purpose?

Back

A blood smear is a laboratory test used to evaluate the health of blood cells and detect abnormalities.

Front

What is the difference between oxygenated and deoxygenated blood?

Back

Oxygenated blood is rich in oxygen and is carried from the lungs to the body; deoxygenated blood is low in oxygen and is carried from the body back to the heart.

Front

What is the role of the pulmonary circulation?

Back

Pulmonary circulation carries deoxygenated blood from the heart to the lungs for oxygenation and back to the heart.
