| Haemoglobin Molecule |
With every breath we take our blood delivers life preserving oxygen to around 37.2 trillion cells in the human body.
Haemoglobin molecules inside red blood cells pick up and carry the oxygen our lungs extract from the air. The blood also carries the carbon dioxide that is emitted from our cells back to the lungs to be expelled by our lungs.
Approximately 25 trillion red blood cells circulate in our bloodstream. Each single red blood cell is packed with ~270 million haemoglobin molecules. To reach some cells, our red blood cells squeeze through narrow capillaries in single file.
As amazing as these facts are, they are also a huge oversimplification of the entire process of maintaining the cells in our body that make up our flesh & bones, organs and brain. Plus, all of that can't begin to explain consciousness and awareness.
Our life is in the blood. To "spill blood" is to take life. It is no wonder that ritual sacrifice involved the blood. Every breath we take our blood performs a miracle that only God could design.
