What are the primary components of the circulatory system?

Lungs, Heart, and Veins
Heart, Arteries, and Veins
Heart, Capillaries, and Lungs
Arteries, Veins, and Muscles

The correct answer is: Heart, Arteries, and Veins

The circulatory system is primarily composed of the heart, arteries, and veins. The heart acts as the central pump that circulates blood throughout the body. Arteries are responsible for carrying oxygen-rich blood away from the heart to various tissues and organs. Veins, on the other hand, transport deoxygenated blood back to the heart. This triad is essential for maintaining efficient blood circulation, ensuring that oxygen and nutrients are delivered to cells while waste products are removed. While the other options mention components that play roles related to circulation, such as the lungs (which are part of the respiratory system and are involved in gas exchange), they do not accurately represent the primary components of the circulatory system itself. Muscles are important for overall bodily function and might influence blood circulation through contraction, but they are not part of the circulatory system's core structure.
