Through your mouth/nose when you breath.
A body of air that stays together is Air mass. (:
It depends on the ambient temperature.
The force that air exerts on your body is called air pressure. This force is a result of the weight of the air above you pressing down on your body.
The answer is a body of air.
It holds all the air for your body and air goes through it to the body.
Air leave the body from organs called the lungs.
To oxygenise the body.
The pocket of air that surrounds the earth is called the earths Atmosphere
If a body is in a vacuum and is filled with air, it will become heavier. If the body is filled with the same air at the same pressure as the outside of the body it will weigh the same. Confused yet? Well try this: In both cases (vacuum or atmosphere), the body will contain more mass with air, yet it will also have less density with more air.
As the diaphragm contracts, air enters the body through the nose and mouth.
The presence of air affects the rate at which a body falls because air resistance acts as a force opposing the motion of the falling body, slowing it down. In the absence of air, such as in a vacuum, there would be no air resistance and the body would fall at a faster rate due to gravity.
The air you breathe out is warm because it has been warmed by your body as it passed through your respiratory system. When you inhale, the air is warmed up to body temperature in your nose and airways, and this warm air is then exhaled back out.
