<h3>What does the amount of blood oxygen mean?</h3>
Your blood oxygen level refers to the quantity of oxygen that is circulating there (also known as blood oxygen saturation).
Since oxygen is required for life, our bodies need a certain amount of it to function properly. Through your mouth or nose, oxygen enters your body when you breathe (inhale), passing through your lungs and into your bloodstream. Every cell in your body receives oxygen when it enters the circulation.
Your body requires energy for all of its processes, including digestion and even thought, and oxygen is necessary for all of your cells to create energy efficiently.
