Why do we breathe?

Breathing is an involuntary activity which we can't control it is required to overall control the coordination of body from the blood to the functioning of it since we breathe oxygen as it is required for the blood to circulate and other body organs to produce energy you can understand this with an example you would have a bike a bike need a fuel which may be petrol and this is required essentially for the working of the bike if the fuel is not provided to the bike then we can't utilise bike in the similar way oxygen is is fuel for our body which can only be consumed by breathing so this is the big reason why we breathe and this is also the reason behind it an involuntary activity performed by involuntary muscles you may also have heared sone facts that we cant stop our breathe to die this is also so the explanation of this fact .thanks......

We breathe through our lungs ?

Oxygen is essential for life. Normal aur contains 21% oxygen, which we breathe into our lungs so it can enter our bloodstream to help with the proper functioning of our tissues and organs. We also breathe as a way to expel carbon dioxide gas, which is a type of waste our bodies produce.

We breathe to the break down of glucose with the help of oxygen to form A. T. P(Adenosine tri phosphate) this is energy packed to gives us energy.
