Yes, it does!
After the trachea, air goes into the primary bronchi, then interpulmonary bronchi, then bronchioles, then terminal bronchioles, then into the alveoli.
The lungs expand drawing in air through the mouth or the nose.
The nose, pharynx, trachea, and bronchi.
what are the 2 pipes air pass through before reaching the alveoli ?
Well, the lungs do the actual "sucking". However, the air enters through the external nares (nostrils) of the nose, the nasal cavity, pharynx (throat) and trachea (windpipe) before reaching the bronchi.
Once you breathe in oxygen through your nose, it travels through the trachea, then to the bronchi. The bronchi helps to get oxygen to your lungs. After the air passes through the bronchi, it travels through the bronchioles which are smaller tubes than the bronchi which are bigger tubes than the bronchioles. From the bronchioles air goes to the alveoli. Then it travels back out through the bronchioles, then through the bronchi until the carbon dioxide waste is out of your system. Hope i helped :)
No, gas cannot pass through glass because glass is impermeable to gases. Glass is a solid material that forms a barrier, preventing the passage of gas molecules.
After passing through the bronchi, expired air moves into the bronchioles, which are smaller air passages within the lungs. From the bronchioles, the air then travels to the alveoli, where gas exchange occurs. Once the oxygen in the air is depleted and carbon dioxide is present, the expired air travels back through the bronchioles and bronchi, eventually exiting the body through the trachea and mouth or nose.
Here's the simplified version: -Nose -Trachea -Bronchi -Broncheoli -Aveoli Here's the more complex one: -Nose -Nasal cavity -Pharynx -Epiglottis -Glottis -Larynx -Trachea -Bronchi -Boncheoli -Aveoli Or the middle version between those: -Nose -Pharynx -Trachea -Bronchi
Bronchi carries air to lung. Mainly o2 and co2.
respiratory zone is from respiratory bronchioles (generation 17-19) to alveolar ducts (generation 20-22) to alveolar sacs (generation 23). It is the site of gas exhange, where velocity of gas is low, and diffusion is the dominant mechanism of gas exchange.
Yes, gas can pass quite easily through cotton wool.
