what is the percentage of water in a human?
18145
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%.
684688
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 their bodies made of water.

The earth has an abundance of water, but unfortunately, only a small percentage (about 0.3 percent), is even usable by humans. The other 99.7 percent is in the oceans, soils, icecaps, and floating in the atmosphere.

Intracellular fluid (2/3 of body water) is fluid contained within cells. In a 72-kg body containing 40 litres of fluid, about 25 litres is intracellular, which amounts to 62.5%.

If we use 70 kg (155 lb) to represent the average adult male, the total volume of water in the body can be calculated to be about 42 L.

When you don't drink enough water, this is what happens to your body. Water is essential for human life. It accounts for for 50-70 per cent of our body weight and is crucial for most bodily functions. Any deficit in normal body water – through dehydration, sickness, exercise or heat stress – can make us feel rotten.

The percent composition of water in the given sample is 20.93 %

Scientists estimate the volume of blood in a human to be approximately 7 percent of body weight. An average adult with a weight of 150 to 180 pounds will contain approximately 1.2 to 1.5 gallons (4.7 to 5.5 liters) of blood.

As these charts and the data table show, the amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth, but the majority of total freshwater on Earth, about 68.7 percent, is held in ice caps and glaciers. Source: Gleick, P. H., 1996: Water resources.

Water is of major importance to all living things; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human adult body is water.
1008943
The average adult loses two to three liters of water a day through natural bodily functions, which is why it's so important to replace that missing water by ingesting two to three liters of fluid a day.
995093
The Earth is a watery place. But just how much water exists on, in, and above our planet? About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water.

Cellular. The distribution of fluid throughout the body can be broken down into two general categories: intracellular fluid and extracellular fluid. Intracellular fluid is approximately 40% of the total body weight. It is the total space within cells primarily defined as the cytoplasm of cells.
837886
Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water.
885963
Adults aged 19 to 30 years The adequate intakes recommended for total water from all sources each day for most adults between 19 and 30 years of age are: 3.7 liters (or about 130 fl oz) for men. 2.7 liters (about 95 fl oz) for women.

How Does Water Affect Your Brain? Your brain is about 75% water. When your brain is functioning on a full reserve of water, you will be able to think faster, be more focused, and experience greater clarity and creativity. Water is also essential for delivering nutrients to the brain and for removing toxins.

Total body water is 60% of body weight (40% intracellular and 20% extracellular). Plasma (blood) volume is 5% of body weight.
