In through the Nostrils into the the nasal cavity where it is heated, humidified and gains turbulance thanks to the concha. The air then moves down through nasopharynx then the laryngeopharynx, through the larynx ant into the Trachea. The trachea runs down the middle of the thorax intill it Bifrucates (splits into two) at the level of T4 to form the two Bronchi. The bronchi go left and right (one into each lung) where the too separate to borm bronioles, which keep branching out until they reach the alveoli. The alveoli are structures that look like bunches of grapes, each grape is called an air sac. As the air leaves it takes the same route in reverse.
Simplified Answer:
Air rich in oxygen enters the nostrils or the mouth. It then passes through the pharynx and then the larynx. Then air goes through the trachea. from there it goes to each bronchi and which branches into bronchiole. From there, it goes the air sacs or alveoli of the lungs.
Notes: Mucus in the nostrils warms, moistens and cleans air so it is better to breathe through your nose!
Well... When you breathe in, oxygen fills your lungs. It travels through your esophagus into your air passage ways to give oxygen to the lungs. Then as you exhale, you breathe out carbon dioxide.
In your mouth/nose.. into your lungs.. back out of your lungs exiting you mouth/nose again...
And if your lucking sometimes it passes through your bum hole. :)
either nose or mouth
trachea
Birds don't inhale air because they don't need to breath.
lung
Trees don't really inhale, they take in gases. Trees take in air but they use the carbon dioxide from the air, and let out oxygen as a waste product of this. They continue doing this all day and night exactly the same
what happens when you inhale is that air goes into your lungs and your lungs get bigger ...Actually, your diaphragm moves to expand the volume of your thoracic cavity, which pulls a partial vacuum on your lungs, causing them to expand FIRST...and THEN the partial vacuum created by your expanded lungs causes air to move into them. When you breath out, it causes the reverse to occur.
It's called breathing... It goes along nice with some crackers, cheese and a glass of tang :)
Mouth/nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli and capillaries.
i can inhale air
the difference between inhale and exhale is when you inhale you get more oxygenthan you exhale
They inhale air. What they extract from the air is oxygen.
the trachea
when you inhale and exhale the air get into the stomach
Alligators are air breathers. They inhale and exhale through their nostrils. Their lungs absorb oxygen from the air that they inhale.
Air is good. Stick with air.
