What are two differences between oxygenated blood and deoxygenated blood? |
Oxygen and Blood
oxgenated blood is bright red in color and travels away from the heart, deoxygenated blood is darker in color and travels back to the heart to be resupplied with 02.
another answer:
Oxygenated blood is blood in which oxygen is attached to the haemoglobin molecules in the red blood cells. It is bright red because the attached oxygen makes the normally blue haemoglobin molecules turn red.
When blood has delivered oxygen to the cells, it is described as deoxygenated. It now looks a very dark red because so many of the haemoglobin molecules have turned blue again. The mixture of blue and red molecules looks dark red to our eyes.
Deoxyhemoglobin (deoxygenated hemoglobin) is dark red; it is a common misconception that blood (at least that without hemocyanin) is blue! (source: https://www.msu.edu/~kalinkat/professionalpages/TechMatrixMaterials/documentarybloodmisconceptions.htm)
