Anatomy is so awesome. The order is fantastic. Our inability at this juncture to understand the massive amount of detail involved in just the function of one single nucleated red cell is overwhelming. Here is such a red cell, electron micrograph originally, which I have pseudo colored, cut pasted,  filled and framed.  Just look for the mitochondria and vesicles, maybe a little RER in the middle and lower left, and hunt up the nuclear pores and look for the areas condensed and euchromatin, then smile.
