Did you know? – Oxygenation

I keep learning random stuff, here and there. I never document these things although they might contribute to an interesting read.

I also have a writing problem. It takes me a lot of time to think through things and condense it into a blog AND I am mightily indisciplined.

So for the benefit of other and in order to be able to push out some content regularly, I am going to start writing ‘Did you know?’ It would generally contain something I learnt that I did not already know.

At time, you might already know it, which is fine; other times you might be surprised. If you like this leave a comment, so I know what all the 12 people reading this think about it.

So here goes…

 

Our blood carries oxygen from our lungs to all of the vital organs in our body. This oxygen is used to burn glucose in the blood stream to produce energy to keep all the organs functioning.

The body does not have any way of detecting the oxygenation levels of blood, but it can detect the CO2 level in the blood.

If you breathe in and hold your breath, you feel this intense need to release your breath because the body wants to push out CO2, not because it seeks Oxygen.

Freedivers use this fact to dive even upto 100 meters without any oxygen. They just keep breathing out enough CO2 and the body is happy!
