When you breathe in, air enters the body (via mouth or nose) and travels down a tube called the windpipe (aka trachea) and into the lungs. When you exhale, carbon dioxide gas is released. Heres something fun for you to try, take a deep breath (inhale with your nose) and try and imagine oxygen going into the lungs. Hope this helped:)

What occurs when the air pressure in the lungs is higher than in the atmosphere?

When the air pressure in the lungs is higher than in the atmosphere, air will flow out of the lungs to equalize the pressure. This is called exhalation. It allows the body to get rid of carbon dioxide and regulate oxygen levels.

Under what condition does air flow goes in to the lungs?

There are about as many atoms of air in your lungs at any moment as there are breaths of air in the atmosphere of?

This statement is not accurate. There are typically billions of atoms in a single breath of air and trillions of breaths in the Earth's atmosphere, making the comparison between the two vastly different. The number of atoms in your lungs is very small compared to the total number of breaths in the atmosphere.


When you inhale does pressure decrease inside or increase?

The act of inhaling is to create low pressure in the lungs, causing the air in the atmosphere to rush in as it is moving from a higher pressure (outside in the atmosphere) to the lower pressure (created in the lungs). However the fact that air does move into the lungs means that there is no net change in pressure.


What internal organs are in direct contact with the atmosphere?

The lungs are the only internal organs that are in direct contact with the atmosphere, as they exchange gases with the air to facilitate respiration.


Why does air rush into the lungs during the process of breathing?

Air enters the lungs because the pressure in the atmosphere is greater than the pressure in the lungs. Lung pressure is lowered by increasing the volume of the lungs. This is achieved by lowering the diaphragm and raising the rib cage.
