What percent of water are humans?
Up to 60\% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73\% water, and the lungs are about 83\% water. The skin contains 64\% water, muscles and kidneys are 79\%, and even the bones are watery: 31\%.
How much of a cell in the human body is composed of water?
70\%
Explanation: The human body like any other living organisms is composed of cells and cells typically are 70\% water.
What organ contains the most water?
Some organs contain much more water than others. The brain and kidneys possess the highest percentage of water; the bones and teeth contain the lowest proportion….Where is water in the body.
| Body part | Water percentage |
|---|---|
| Kidneys | 80–85\% |
| Heart | 75–80\% |
| Lungs | 75–80\% |
| Muscles | 70–75\% |
Do humans need more water than other mammals?
But what is sweated out has to be replaced. Originally Answered: Why do humans have to have water much more regularly than other mammals or other organisms? Because we evolved in areas where water was relatively plentiful, and we use water as a cooling system, meaning we can dehydrate much quicker than other animals.

Body composition varies according to gender and fitness level, because fatty tissue contains less water than lean tissue. The average adult male is about 60\% water. The average adult woman is about 55\% water because women naturally have more fatty tissue than men.
What is the most abundant molecule in the human body?
Although liquid water is the most abundant molecule in the body, additional water is found in hydrated compounds. About 30-40\% of the weight of the human body is the skeleton, but when the bound water is removed, either by chemical desiccation or heat, half the weight is lost.
