If you recall from basis chemistry, water is made up of 2 hydrogens and 1 oxygen. The reason why we can't breathe underwater is because the oxygen molecule is already bound to the hydrogen molecules. Oxygen in this form is useless to our lungs. Our lungs can't extract oxygen from water

If babies can breathe in water in your belly then why cant we breathe under water?
Babies don't breathe the water in the womb. Their mothers breathe for them, and supply them with oxygen through the umbilical cord. Babies don't start breathing until they are born. Humans, well no mammal can breathe water, because our lungs can't get any oxygen from it. Although they do the same job, gills work in a slightly different manner, which allows fish to get oxygen from the water the way we get it from the air.
Why cant earthworms live in water or soil that is saturated?
Earthworms require oxygen to breathe, and when soil is saturated with water, there is not enough air present for the earthworms to survive. The excess water limits the movement of air in the soil, causing oxygen levels to drop and suffocating the earthworms.
Can a goldfish drown?
A fish would drown in water that is not sufficiently oxygenated.Actually the question is not a silly as it sounds and does not only occur when there is not enough oxygen in the water. Under the right conditions (or in this case, the wrong conditions) a fish can actually drown just as surely as a human can. Drowning is caused by suffocation in a body of water, it is accurate to say a fish that is starved of oxygen while in the water has in fact drowned. Fish breathe by taking in oxygen from the water and if the body of water they are living has a depleted oxygen supply, then the fish must either move to a new, oxygen rich area, or drown. During summer months in particular, the deep lakes' oxygen supply can easily become depleted due to animal respiration and decay of vegetation. This causes large groups of fish to die, as they very often refuse to move out of the oxygen-less region. There are even some species of fish that have developed such complex respiratory systems that they can only breath outside of the water. Fish, such as the Climbing Perch fish, can get out of a body of water and survive on land, but many need to breathe our air as well as gaining oxygen in the water. If these fish are forced to stay under water, they will not gain the necessary oxygen they need to survive, resulting in the fish drowning. The Climbing Perch have a respiratory system that is dependent on our oxygen rich air and the fish will drown if forced to stay underwater for to long, no matter how much oxygen is in the water.
How can a human adapt to underwater pressure?
get a oxy tank .Unless you have gills, you are going to need access to oxygen. There is the traditional snorkeling mask, a scuba tank, or more recently, a new breathing apparatus that doesn't use tanks or tubes."An Israeli Inventor has developed a breathing apparatus that will allow breathing underwater without the assistance of compressed air tanks. This new invention will use the relatively small amounts of air that already exist in water to supply oxygen to both scuba divers and submarines. The invention has already captured the interest of most major diving manufacturers as well as the Israeli Navy."Source: http://www.isracast.com/article.aspx?id=63Well, you can't really breathe underwater. You can hold you breathe underwater but most people can't do that for more than a minute. If you really want to breathe underwater, try scuba diving on vacation or deep sea diving or something like that. Or, you can professionally become a person who does that for a living.
How are plants your partners in breathing?
Plants use sunlight to perform photosynthesis, absorbing carbon dioxide and releasing oxygen as a byproduct. Through this process, plants help to replenish the oxygen in the atmosphere that humans and animals need to breathe. This symbiotic relationship between plants and animals ensures a constant supply of fresh oxygen for all living organisms.
Why can't you breathe underwater to say alive?
The reason you cant breathe under water is because people is made to breathe oxygen, water composes oxygen.
Why cant you breathe the oxygen in the crust?
the majority of oxygen is found in water therefore you cannot breathe the oxygen in water
Do mammals have gills and can mammals breathe under water?

Can hermit crabs breathe under water and oxygen?
no they breath oxygen like us
Why don't cats breathe underwater?
cause they cant dont be so stupid!
Why do you drown when you breathe in water?
Humans are developed to breathe air by gas exchange in the lungs. We do not have the physical capability, like fish, to have a gas exchange with water. -- Also, because your heart is pumping and you need a lot of oxygen for your blood. The same with any physical activity.
Why cant the blue whale breathe under water?
Blue whales are mammals. They breathe air with lungs, pretty much just like you and I. When they dive, they hold their breath.

Why cant you breathe on Venus?
It's mostly carbon dioxide and a little nitrogen. We need oxygen and a lot of nitrogen.
