When you inhale, air flows through the nasal cavity or mouth, then travels down the trachea. It enters the bronchi, which branch into the bronchioles in the lungs. Finally, the air reaches the alveoli, where gas exchange occurs. Thus, the five organs involved are the nasal cavity/mouth, trachea, bronchi, bronchioles, and alveoli.
The lungs are the primary organs responsible for extracting oxygen from the air you breathe. When you inhale, oxygen from the air is transferred into the bloodstream through tiny air sacs in the lungs called alveoli. These alveoli exchange oxygen for carbon dioxide, which is then exhaled out of the body.
Alligators are air breathers. They inhale and exhale through their nostrils. Their lungs absorb oxygen from the air that they inhale.

Kookaburras, like other birds, respire through a system of lungs and air sacs. When they inhale, air flows into the air sacs, where it is stored. During exhalation, the air moves from the air sacs through the lungs, allowing for efficient gas exchange. This unique respiratory system enables them to extract oxygen effectively, supporting their active lifestyle.
The oxygen from the air they inhale is distributed to the body parts through the blood stream. The blood picks up carbon dioxide and it is exhaled into the environment.

exhale
It flows downwards because it is cold and cold air sinkse. The most important reason why it flows downwards is that dry ice is made of CO2 / carbon dioxide which = 1.5 times heavier than the air that we inhale.
Air enters through the mouth or nose and travels through the trachea then it flows through the large tubes called what?
The air flows into the furnace through the return ducts, gets heated by the furnace, and then flows out through the supply ducts to heat the home.
