The MAJOR organs in the circulatory system are three. Heart, Lungs, and Brain. Without any one of these three organs the circulatory system ceases to function.
Actually, Left ventricle pumps blood to body through the vessels, goes to right atrium, goes to right ventricle where it goes through the lung to get oxygen, goes to left atrium, then back to left ventricle.
Brain is nervour system, lungs are respitory system.
... The major organs of the circulatory system are the heart, blood, and blood vessels.

THE ANSWER IS THE HEARTand the veins and the googleGeeves would like to suggest that there are three essential aspects to the circulatory system: Heart, lungs, and brain. Without any one of these organs the circulatory system would cease to function.
The blood and its content is not an organ in the system, veins and capillaries carrying to and from organs reliant on the heart and its circulatory system are not organs. However, its considerd that All the circulatory system IS an organ as a whole.
