It gets transported from your lungs into your blood as the blood passes thru the lungs. As the Oxygen runs low at the same time the levels of CO2 build up in the lungs and both things make you need to take a breath

It keeps to extend. once you inhale, you breath in a mixture of despite air is obtainable. with any luck, it is a minimum of 19% oxygen in the different case there is not any factor to preserving your breath. Your lungs circulate oxygen from the air on your lungs into your blood circulate, changing it for carbon dioxide. As this occurs, the oxygen proportion of the air final on your lungs decreases and the carbon dioxide will develop. The longer you carry your breath the slower the cost this occurs because of the fact the quantity of oxygen obtainable is inadequate.

we cant hold our breaths for long that a clear indication that the concentration of oxygen in the lungs keeps reducing as we slowly consume all the oxygen that was inhaled.

Oxygen concentration decreases as oxygen diffuses into the capillaries.

As you hold your breath - the oxygen continues to exhange out
with carbon dioxide - when it's used up - you better exhale
and get fresh O2
or you will faint or passout
suffocation?

well, the Oxy. is used up in the tissues and the concentration decreases...the CO2 concentration increases and practically, this limits the time for which V can hold our breath...
