Does the cardiovascular system and respiratory system share responsibility of supplying oxygen and eliminating carbon dioxide?

The simplest way I can explain this is when we take a breath oxygen enters our lungs and is delivered in the bloodstream. The heart pumps blood through arteries that circulate this oxygenated blood to the capillaries found in all tissues. Then veins return deoxygenated blood (where carbon dioxide is found) to the lungs to be exhaled Sara, RN.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
