Our bodies consist mostly of water (65-90%), and here is more complete chemical composition of human body by elements, in dry weight %:
Carbon... 61.7
Nitrogen.. 11.0
Oxygen.. 9.3
Hydrogen... 5.7
Calcium.. 5.0
Phosphorus..3.3
Potassium.. 1.3
Sulfur.. 1.0
Chlorine.. 0.7
Sodium.. 0.7

Hi !!!!
Let's take a look at ourselves with an extremely high powered electron microscope. In so doing we can see that every part of our bodies is made up of the same thing. And that is "Cells". Human beings are made up of roughly 60 trillion cells.
Say CHeese ;)

The human is a creature like an animal. it is made of proteins, carbons and other minerals as well as h2o and nerve currents as well as sensory mechanisms.

Different people have different percentages of their bodies made up of
water. Babies have the most, being born at about 78%. By one year of age,
that amound drops to about 65%. In adult men, about 60% of their bodies
are water. However, fat tissue does not have as much water as lean tissue.
In adult women, fat makes up more of the body than men, so they have about
55% of thier bodies made of water. Fat men also have less water (as a
percentage) than thin men.
So you can see three possible reasons for the discrepancies you have found:
1) Babies and kids have more water (as a percantage) than adults.
2) Women have less water than men (as a percentage).
3) Fat people have less water than thin people (as a percentage).
A forth reason is that different people measure per cent water a little
differently, causing small differences in the answer.
Of course, there are the muscles, tendons, nerve fibers, bones, and organs. I hope this is the type of information you are looking for,

The same thing as anything else; Matter - Molecules - Atoms - Energy. If you want proof - then place your hand under a high powered microscope.

Organs, tissues, cells and the components of cells that make cells work!
Tissues include muscle and dermal tissue (skin).
All bodies are comprised of different systems: cardiovascular (heart and blood vessels), skeletal (your skeleton), digestive (how your body turns food into energy), reproductive (how babies are made), nervous (brain, nerves, spine, etc) and more.

There all wrong, all we are is protein and carbohydrates, thats all. Thats why they believe they can make us beam up Scottie in the future when they can manipulate us.

Dude you have several questions like this and they all end in off- hello its what are humans made OF???? Not off- OF. And why are you asking questions like this when things like that are easily looked up. DUH
