The blue (on the right) is oxygenated and the red (on the left) is deoxygenated? answer if this right: )

Blue (right) is deoxygenated and Red (left) is oxygenated.

think of it as like a cartoon when a character cant breathe, they turn purple or blue. While in real life, deoxygenated blood is not actually blue and it is a deep red and the oxygenated blood is bright red. They just show it as blue to help you differentiate.
