The six major organs fed by the circulatory system include the brain, heart, lungs, liver, kidneys, and intestines. The circulatory system delivers oxygen, nutrients, and hormones to these organs while also removing waste products and carbon dioxide from them.
heart is the organ , you may not believe but blood is tissue.
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 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.
