How does air from the atmosphere get into lungs?

Answer 1

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:)

Answer 2

when you breath in a flap in your throat opens up, the air goes through this flap and into your lungs this is why it is bad to speak whilst eating because the food can go into the lungs this is also how tar from cigarettes gets into the lungs

Answer 3

The nose is the best route for air to get into the lungs, as it is a better filter than the mouth. The nose decreases the amount of irritants that reach the lungs, whilst also heating and adding moisture to the air.
Mouth breathing is usually needed when exercising or when more air is needed, because the nose is not the most efficient way of getting large amounts of air into the lungs.

Answer 4

your lungs are like two balloons that inflate and deflate. We can get air into our lungs by the mechanical method of ''breathing'' Once we inhale (bring air in) our muscles between our ribcage (intercostal muscles) contract making the ribcage move upwards and outwards, our diaphragm also contracts and moves downwards therefore over all increasing the volume in the lungs finally the air rushes in.

Answer 5

Your diaphragm (underneath your lungs) contracts downwards which pull air into your lungs. Imagine it like when you squeeze a bottle and when you let go it suck in air. Also when you are doing exercise or breathing heavily your external muscles aid your diaphragm by pulling your lungs outwards hence more air going into your lungs :).

Answer 6

When the diaphragm and muscles attached to the ribs expand the chest cavity low pressure is created and air moves in to fill it.

Answer 7

air gets into our lungs when we breath
