Some of the earliest discoveries were from the 16th BCE (before the common era). William harvey first described the circulation of blood.
blood, heart, blood vessels
yes..........
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
The organs of the circulatory system include the heart, blood, and blood vessels. The heart is the pump that takes the oxygenated blood through the blood vessels to supply the cells with energy.
William Harvey was first to demonstrate the functions of the heart and the complete circulation of the blood,
he discovered blood vessels in his patients and predicted that they linked the heart and lungs and carried air and blood
The heart pumps oxygenated blood to all parts of the body through the vessels, delivering nutrients and removing waste products. The blood vessels, including arteries, veins, and capillaries, help transport blood around the body and maintain blood pressure. Together, the heart, blood, and vessels work to support the body's circulation and maintain essential functions.
The cardiovascular system includes the heart and blood vessels. Its main functions include circulating oxygen, nutrients, and hormones to cells throughout the body, as well as removing waste products.

The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through the blood vessels to deliver oxygen and nutrients to cells and remove waste products. The blood vessels, including arteries, veins, and capillaries, act as a network to transport blood throughout the body.
The heart blood and the vessels are in your body and everyone has them including you too.
