By Anne Marie Helmenstine, Ph.D. Answer: Most of the human body is made up of water, H 2 O, 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.You may also wish to view the element composition of an average human body by mass. 1  Oxygen (65%). 2  Carbon (18%).arbon, 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.
