Which organs are involved in the circulatory system and how do they work together to transport blood throughout the body?

The main organs involved in the circulatory system are the heart, blood vessels, and blood. The heart pumps oxygen-rich blood to the body through arteries, which carry blood away from the heart. The blood then travels through smaller vessels called capillaries, where oxygen and nutrients are exchanged with tissues. The blood returns to the heart through veins, completing the circulation process. This continuous cycle ensures that all parts of the body receive the necessary oxygen and nutrients for proper functioning.
