make up 99.7% of the human body.
Heavier elements tend to sink to the center of the earth.

Carbon, Nitrogen, Oxygen and Hyrdrogen constitute 87.7% of the mass.
This is explained by their great tendency to combine in large randomly arranged,
but stable structures that represent the main structural masses
of the flexible tissues of the body.
Add Calcium, a well known constituent of bone, and you account for a grand total of 92.7% of the mass.
Potassium, Sodium and Cloride are the main small solutes in bodily fluids, bringing us to 95.4%, and finally..
phosphorus, important in DNA, the purveyor of one's lineage, brings us to 98.7%.
So how, you ask, can these four main elements, plus 5 more minor ones, plus assorted incidentals be arranged in these amazing arrays of form?
the 69nth CRC handbook of Chemistry and Physics gives
the area of the world's oceans as 361e6 km2 and the mean depth at 3794m
multiplying the two we get the volume 1.369e18 cubic meters
that's the same as 1.369e24 cc's (mL, gH2O) or 7.6056e22 moles
