How breathing works? And how is it so fast?

Question

Between breathing in and out there’s a gap of two or three seconds.

How is it possible that every cell in our body absorves O2, uses it, and expels CO2?

I can’t even think of the air going from my nose to my big toe that fast.

Answer 1

See it like a big cafeteria with food trays gotten on one end, and dumped on the other. With your breath in you get a tray of food. Now sith your next breath out you haven’t eaten that food yet, it just entered your body. But it keeps going. You ealk towards your table, you eat the food, you walk towards the trashcan to throw the trash out.

While you do so (walking, sitting, eating, walking) other people are also getting trays of food (breaths with oxygen). It takes a while for the oxygen to be taken in by your body, so there might be 100 breaths between when you take in a specific oxygen cell to where it’s exchanged for a carbondioxide cell that will be carried out. But because there is a constant flow of people getting new food trays and people dumping their ‘eaten’ food trays, there id a constant flow.

So no, the two of three seconds does not use the one specific oxygen cell, you are correct in the fact that it doesn’t go from your nose to your toe that fast. It’s a conveyer belt that is constantly goving you new food trays while simultaneously dumping empty food trays with trash.
