so i know that red blood cells carry oxygen in hemoglobin, and the red blood cells are delivered to cells, but does the red blood cell derectly transfer oxygen to the cell? or does it diffuse to plasma first? can someone explain what technically happens to get oxygen from red blood cells into the cells of thte body?

 

 

You might find this article from The Journal of Experimental Biology helpful.

 

 

It's called "The dual roles of red blood cells in tissue oxygen delivery: oxygen carriers and regulators of local blood flow". It's pretty technical but you can find a summary answer at the very beginning.
