a heart problem
You Die
Grasshoppers have an open circulatory system, and worms have a closed circulatory system. There you go. :)
if the valves failed then the blood would go in the wrong direction.
The lungs are part of the respiratory system! they help the circulatory by giving oxygen, but they are just respiratory.
Carry's oxygen through the lungs so we can breathe and then go to the circulatory
Into the bloodstream.

Some of the problems of the circulatory system are; angina (when the heart stops working), aortic aneurysm (when the aorta explodes), arrhythmia (when the heart doesn't have a very good beat rhythm), high blood pressure (this is easy to remember, it says exactly what it means), peripheral vascular disease (when blood doesn't get to the outsider areas of the body). All of these terms are not very scientific. But good for people like me to be able to understand :) So if you need scientific terms don't use these ones.
when the blood follows one circuit pathway through the body , it is termed as single circuit plan
It makes your blood go black and bubble.
Nutrients from the digestive system enter the circulatory system. From there, they are transported to all body cells.
Then the system you are working with will have the wrong process causing things to go wrong
