Which of the following is NOT a basic part of the circulatory system?

Heart
Lungs
Arteries
Veins

The correct answer is: Lungs

The circulatory system primarily consists of the heart, blood vessels (including arteries and veins), and blood. The heart is the central pump that circulates blood throughout the body, while arteries carry oxygenated blood away from the heart to the tissues, and veins return deoxygenated blood back to the heart. The lungs, while vital for oxygen exchange and part of the respiratory system, do not constitute a component of the circulatory system. They act as a site for gas exchange where blood receives oxygen and releases carbon dioxide, but the lungs themselves are not directly involved in the distribution of blood or the mechanics of circulation. Understanding this distinction helps clarify the structure and function of the circulatory system compared to other systems in the body.
