The amount of water vapor in the air varies depending on weather conditions. In extremely dry conditions there can be almost no water vapor, while in tropical areas water vapor can comprise more than 4% of the air by volume.
Saturated air at 30° C (82°F) can hold about 30 grams (1 ounce avoirdupois) of water per cubic meter of air. At 42° (108°F), the saturation point is about 55 grams, or nearly twice as much.
The human body is made up of about 60 water on average.
The average adult human body is made up of about 60 water, and blood is about 92 water.
The human blood is made up of about 55 plasma, which is mostly water. This means that approximately 55 of the blood volume is water.
Approximately 78 of the air we breathe is nitrogen.
Approximately 60 of the human body is made up of water.
i don't think humans breathe in any water but they do breath out water
It's the water vapor in your breath, after it becomes liquid water. Warmer air is able to hold more water vapor than cooler air. When you breathe onto a cold surface, the air in your breath is cooled, and it can't then hold as much water vapor as it did when it was warm. So some of the vapor condenses out ... becomes water instead of vapor ... and the condensed water collects on the glass. Exactly the same process is responsible when you exhale into cold air and you "see your breath".
Gills are organs in which carbon dioxide from the animal is exchanged for oxygen in the water.

Air you breathe out is denser than helium. This is because exhaled air contains a higher concentration of carbon dioxide and water vapor, which are denser than the gases in the atmosphere. Helium is much lighter than air and tends to rise up.
You can see water vapour in the air, as when a kettle or pan boils, or when you breathe out into cold air. It depends on the temperature balance between the vapour and the surrounding air.

The ratio of water vapor in a volume of air relative to how much water vapor that volume of air is capable of holding is called relative humidity. It is expressed as a percentage and provides insight into how close the air is to being saturated with water vapor.
According to many scientists and researches, people cannot breathe in water because water molecules cannot be absorbed by human lungs. Humans have lungs that do not have enough surface area to absorb enough oxygen from water. Our lungs are more much more adapted to air than water.
Yes, water vapor does have mass. Water vapor is a gas composed of water molecules, and like all matter, it has mass. However, the mass of water vapor is much lighter compared to liquid water.
Dolphins are mammals. They breathe air with lungs, pretty much just like you and I. They can't breathe water. When they dive they hold their breath.
