The three parts of the circulatory system are:

1. The heart - beats 60 to 100 times per minute

2. The blood vessels - about 60 000 miles / 96561 km of vessels, including the arteries, veins, and capillaries. Arterioles and venules are small arteries and veins, respectively.

3. The blood - average of 6 litres / 12.7 pints

Parts of the heart include the Septum, right and left atria (singular "atrium), and right and left ventricles. Valves in the heart include the tricuspid Valve, bicuspid Valve, Aortic Semilunar Valve and Pulmonary Semilunar Valve. Major blood vessels include the Inferior Vena Cava, Superior Vena Cava, Pulmonary Artery, Pulmonary Veins, Coronary Artery, and Aorta.

The heart is the center or the main source of the circulatory system. It pumps blood throughout a network of blood vessels. An artery is a blood vessel that carries blood away from the heart. Capillaries are very thin vessels that gases, nutrients, and wastes pass to body cells. A vein is a blood vessel that carries blood to the heart.

The body's blood vessels can be subdivided functionally into the systemic system and the pulmonary system.

The circulatory system has the work of transporting oxygen, water and nutrients to cells and carrying away wastes from those cells.
The 3 parts of the circulatory system are the heart, the blood vessels and the blood. The heart is the pump that circulates the blood throughout the body. The blood vessels are the arteries, veins, and capillaries that the blood travels through. The blood supplies our cells with oxygen, nutrients, and takes away waste.

The circulatory system is composed of the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through the blood vessels to deliver oxygen and nutrients to cells throughout the body and remove waste products.
