How Much of Human is Water?
Water is a crucial component of the human body, and it is vital for the proper functioning of all our organs and systems. The amount of water present in the human body varies depending on different factors such as age, weight, and sex.
The human body is made up of about 60% water. This means that for an adult weighing 70kg, approximately 42 liters of water make up their body. The percentage of water in babies, however, is much higher, making up about 75% of their body weight. In contrast, the elderly have a lower percentage of water, making up only about 50% of their body weight.
It’s essential to note that the water in the human body is not just plain water but a combination of different fluids. These fluids include blood, urine, digestive juices, sweat, and tears, among others. Therefore, the percentage of water in the human body depends on the type of fluid being considered.
Water in Different Organs
The percentage of water in different organs of the human body varies. Some organs have a higher water content than others. For example, the brain and heart have a water content of about 73%, while muscles have a water content of about 79%. Bones, on the other hand, have a water content of only 31%.
The table below shows the percentage of water in different organs of the human body:
| Organ | % of Water |
|---|---|
| Brain and Heart | 73% |
| Muscles | 79% |
| Lungs | 83% |
| Kidneys | 79% |
