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!
What else can I help you with?
What takes in oxygen?
Humans take in oxygen and breathe out carbon dioxide.
Does aerobic respiration takes place in humans?
YES! Aerobic respiration is basically respiration using oxygen - we breathe in oxygen - so aerobic respiration does take place in humans.
What path does light take?
light takes a straight path.
What is the path when you take a breathe in?
It goes down your larynx, into the bronchial, then bronchi, then the aveoli.
What do you breathe when you breathe out?
Humans breathe out carbon dioxide, the whole world runs in a motion, for example plants breathe carbon dioxide, we breathe in oxygen. Even fish breathe oxygen. They take the oxygen out of the water. So we breathe in what plants breathe out and plants breathe in what we breathe out.
What does trees let off for humans to breath in?
Trees take in Carbon Dioxide and release Oxygen. We as humans breathe in this Oxygen.
Why forests are good for humans?
Because they take in the co2 that we breathe out and give off oxygen
How does carbon dioxide cycle between living things?
Humans breathe in oxygen, which plants produce, and breathe out carbon dioxide, which plants take in.
How long does it take to breathe in and breathe out?
It takes approximately 3 seconds to breathe in and 3 seconds to breath out for regular breathing. It will be less time the faster your respiration rate is.
The path the planet takes around the sun?
The path the planets take around the sun, is called a orbit.
What humans do to plants?
Humans, and actually all other animals, breathe out carbon dioxide. Plants take in this carbon dioxide and combine it with water and sunlight to make food in a process called photosynthesis. Luckily, a byproduct of this process is oxygen, which humans and other animals breathe in. Then we breathe out carbon dioxide, and the wondrous cycle continues.
Humans breathing is a factor that causes an imbalance in the carbon cycle?
No, this is not true. Human breathing is part of the carbon cycle. We breathe it in, (and we take it in by eating and drinking) and we breathe it out.
