percentages of what the human body is made of?

Answer 1

I am not sure you wanted to know the % of water in our body - as people so far wrote here. If you did, then I found a better "estimate":

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.

Also, water content differs throughout the body. Blood is made up of 83 percent water, bones are 22 percent water, and muscle is 75 percent water. The human brain is about 75 percent water.

If the question was about fat percentage, than the answer is different. This varies and depends from whether you are a man or a woman, from your age and from your level of fitness. For example, men athletes have between 6 and 13% fat, whereas the body of women athletes contains about 14-20% fat. Obese people on the other hand, present a percentage of fat equal or above 25%.

Hope this help.

Answer 2

A. An average adult body is 50 to 65 percent water -- that's roughly 45 quarts. Men are more watery than women. A man's body is 60 to 65 percent water, compared to 50 to 60 percent for a woman. In infants, the figure is a whopping 70 percent according to statistics compiled by the International Bottled Water Association.
