Pulmonary = lungs Circulatory = blood Without oxygen in the blood, there's not much point in having a circulatory system to pump it around, now, is there? And how can a circulatory system function if it has no energy because it has no oxygen? than you!
Your body transports blood (water) throughout the body!
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.
A system is a set of interconnected components or parts that work together to achieve a common goal. It can be physical, such as a computer system, or abstract, such as a social system. The components of a system interact with each other and are dependent on each other to function as a whole.
The circulatory system transports blood loaded with oxygen and nutrients it brings food to each cell of the body
The valves keep blood flowing in one direction. And there are even valves in the veins. The system is called a circulatory system and the system must keep going in a circle to function properly.

each and every moment.
Not clear on which 3 classes are the "major ones", but Polyplacophorans, Gastropods, and Bivalves have an open circulatory system while Cephalopods have a closed circulatory system.
Some sort of system has to carry the nutrients to each cell and carry away their wastes. This job is given to the circulatory system.

organs are interdependent because they must work together to function, otherwise, we won't work properly. they cannot work alone. organs work together and organ systems work with another to function.
