What are the main organs of the circulatory system?

The main organs of the circulatory system are the heart, blood, and blood vessels. These components work together to transport substances throughout the body.

The heart is a muscular organ that pumps blood continuously to all parts of the body.

Blood acts as the transport medium and carries oxygen, nutrients, hormones, and waste materials.

Blood vessels form a network through which blood flows. They are of three main types: arteries, veins, and capillaries. Arteries carry blood away from the heart, veins bring blood back to the heart, and capillaries allow the exchange of substances between blood and body tissues.

Together, these organs ensure proper circulation and maintain the body’s internal balance.
