Your body takes what it needs and then the rest gets exhaled out and goes into the atmosphere.
When air gets inside your body, your diaphragm exhales up and down.
It goes to the air
All of them
most of the time if you get an air bubble you die
you need to have some water.
oxygen
sun: because we need vitamin D and the sun happens to give it. air: because we need oxygen to breath or we die. water: because the cells in our body need it to transfer nutrients throughout our bodies. soil: because we can plant food on it to eat.
mainly oxygen there are several other gases that our body needs.
its not so much the air that you need. but you do need something that is in it. oxygen is like a food for cells. the blood carys the oxygen around the body. there is also carbon dioxide (C02) in air. and that's what you breath out.but not everything, but most things.
when air enters the body through the drips we take it may lead to many health problems.
Sunlight, air, water.
it is used in the body. It it transported around to all the cells so they can function.
