Based on the provided information, the human organ with the most water content among those listed is the lungs.
Water is essential for life, making up a significant portion of the human body. Its distribution varies across different tissues and organs.
Water Content in Human Organs
According to data compiled by Mitchell and others (1945) and referenced by the U.S. Geological Survey, the percentage of water in various human organs is as follows:
- Brain: 73%
- Heart: 73%
- Lungs: 83%
- Skin: 64%
- Muscles: 79%
- Kidneys: 79%
- Bones: 31%
Let's look at these percentages clearly:
| Organ | Water Content (%) |
|---|---|
| Brain | 73 |
| Heart | 73 |
| Lungs | 83 |
| Skin | 64 |
| Muscles | 79 |
| Kidneys | 79 |
| Bones | 31 |
Comparing these figures, the lungs contain the highest percentage of water at 83%. This high water content is vital for their function, particularly in facilitating gas exchange (oxygen and carbon dioxide) across moist surfaces.
For more details, you can refer to the U.S. Geological Survey's information on Water and the Human Body.
While organs like the brain and heart also have high water content (73%), and muscles and kidneys are 79%, the lungs stand out with the highest percentage among this specific group of organs listed in the reference. Bones, in contrast, have the lowest water content at 31%.
Understanding the water composition of different organs highlights the diverse roles water plays throughout the body, from metabolic processes to structural integrity.
