Elements of the Body Revisited

The ratios of oxygen, carbon, hydrogen, and nitrogen inside the human body are fairly common knowledge, but what I'm looking for is a breakdown of where these (and other essential elements ... particularly potassium, magnesium, sodium, and calcium) are stored in the body.

I'm looking for an elemental makeup (by mass) of the Bones, Kidney, Liver, Brain, Skin, Blood, Heart, Lungs, and Muscles.
Anyone know where I might find one?

You forgot of a very important element like Phosphorus, without it you would not have a DNA .
Are Sulfur and Iron important ?
 
"Most of the human body is made up of water, H2O, with cells consisting of 65-90% water by weight. Therefore, it isn't surprising that most of a human body's mass is oxygen. Carbon, the basic unit for organic molecules, comes in second. 99% of the mass of the human body is made up of just six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.

1.Oxygen (65%)
2.Carbon (18%)
3.Hydrogen (10%)
4.Nitrogen (3%)
5.Calcium (1.5%)
6.Phosphorus (1.0%)
7.Potassium (0.35%)
8.Sulfur (0.25%)
9.Sodium (0.15%)
10.Magnesium (0.05%)
11.Copper, Zinc, Selenium, Molybdenum, Fluorine, Chlorine, Iodine, Manganese, Cobalt, Iron (0.70%)
12.Lithium, Strontium, Aluminum, Silicon, Lead, Vanadium, Arsenic, Bromine (trace amounts)

Those're the common ratios I was talking about, I'm just interested in potassium, magnesium, sodium, and calcium. Specifically, I'm trying to figure out where in the body those elements are focused, although a general breakdown of those percentages linked above by organ would be wholly appreciated.

Ex) The liver is composed of x % iron, y % carbon, z % oxygen, you get the gist
 
Do some searches with the terms “trace elements human body” or similar phrases. Doing so I found these within a matter of minutes.....
