Sam immediately went back into the divine dimension after the confirmation as he looked at the simulated body that was hovering in the space.
He started checking all the organs, muscle tissues. Even if he cannot have a physical sensation, the body he simulated is the body he observed, so it is pretty close. But none of these showed any difference than a normal human body. They act the same way, they work the same way.
The only difference is the cellular structure.
Just like his own body. Sam's body is also different on a cellular level but there is not much difference in the nature of the operation. Except for some specific functions, the eyes because of the Sky's bloodline, the nose because of Raiju's bloodline, and the stomach because of Mia's bloodline.
They have small changes in their functions, but the lungs are the only ones whose change could be seen beyond a cellular level.
