Basic chemistry of breathing

4 important elements are involved in our breathing

Oxygen – O
Hydrogen – H
Nitrogen – N
Carbon – C

The purpose of breathing is to supply oxygen to the body, which is needed to generate energy and to dispose carbon dioxide, which is a byproduct of the energy generation.

The air we inhale is about 80% nitrogen (N) and 20% oxygen (O2). Once air gets into the lungs, part of the oxygen (O2) is exchanged with carbon dioxide (CO2) from the bloodstream using tiny bubbles that function as exchange chambers. The air we exhale is about ~ 80% nitrogen (N) 16% oxygen (O2) and 4% carbon dioxide (CO2).

Trees and plants “inhale” carbon dioxide (CO2). They “drink” water (H2O) via their roots. They use “solar panels” – their leaves, to collect energy from the sun and use this energy to break down the (CO2). Plants “exhale” oxygen (O2) and keep the carbon (C) with which they hydrate, react with (H2O). The result is carbohydrates (C-H-O), the building blocks of trees and plants.

The carbohydrates that we eat, are compounds made from carbon, hydrogen and oxygen (C-H-O). When the oxygen (O2) we breath reacts with the hydrogen (H) of the carbohydrates, needed energy is released in our body and one of the byproducts of this reaction, is carbon dioxide (CO2) which is expelled when we exhale.

    Hello Sir!
    You mention that Some breathing exercises are meant to calm-down and others are meat to stimulate.
    My question is: which are for stimulate and which for calm down?
    Thank you Sir!
