When one inhales, oxygen-rich air reaches the alveoliwhich are air sacs located in the lungs. The oxygen diffusesthrough the thin walls of the alveoli through the thin walls of the capillaries. The blood rich in oxygen carries it to the heart through the pulmonary vein. The heart pumps it through all parts of the body.
Meanwhile, deoxygenated blood rich in carbon dioxide reaches the pulmonary artery of the heart from various parts of the body. The blood diffuses through the capillary wall into the alveoli, and is exhaled.
Path of air (during inhalation) before reaching the alveoli:
When air passes through your lungs it is called respiration.
The air that is inhaled passes through the throat. More specifically, it passes through the trachea on its way to the lungs.
trachea
Air passes through your nose and mouth and into your windpipe, also known as the trachea, which carries the air to your lungs for breathing.
throat, bronchies, lungs
First it passes through the tracea, then the bronchus, then alveoli and then finally the air sac.
When air passes through the respiratory system, it travels through the nose or mouth, down the trachea (windpipe), and into the lungs where gas exchange occurs. Oxygen from the air is absorbed into the bloodstream, and carbon dioxide is released from the bloodstream into the air to be exhaled.
Air passes through: 1. Nose or Mouth 2. Nasal cavity 3. Pharynx 4. Larynx 5. Trachea (in throat) 6. Bronchus (in chest) 7. Bronchioles (finer tubes inside lungs) into the alveoli (tiny pockets inside lungs). The o2/co2 exchange occurs in the alveoli where they interface with capillaries. Hope this helps.
No. It is warmed to near body temperature as it passes through the nose, throat, and bronchi.
nostril,pharynx and bronchi
Its function is to take dust out of the air as it passes through your nostrils to the lungs. That's why it is sticky.
Air passes from the environment into the nose/mouth, through the nasopharynx and oropharynx, into the glottis, trachea, bronchi and its bifurcations, and into the alveoli of the lungs.
