How is the blood in the pulmonary artery different from blood in other arteries?

The pulmonary artery runs from the heart to the lungs. It is the only artery that doesn't carry oxygenated blood. That makes it a darker red than the blood in other arteries, so it looks blue under your skin.

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.
