drow the three major parst of circulatory system
The three major parts of the circulatory system are the heart, the blood, and the 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 three main parts of the circulatory system are the heart, blood vessels, and blood.
In cephalopods like octopuses, the circulatory system is closed, with blood contained in vessels. Bivalves like clams have an open circulatory system where blood is pumped into a hemocoel. Gastropods, such as snails, have a mix of closed and open circulatory systems, with a heart that pumps blood through vessels but also into spaces around organs.
