Breathing.
Oxygen and carbon dioxide increase and decrease in the lungs.
To increase the oxygen intake to stimulate the heart and lungs. You can try exercises like pursed-lip breathing and deep belly breathing to open your airways and increase the amount of oxygen in your body.
The alveoli.The Respiratory System
If you held your breath, the concentration of oxygen in your lungs would gradually decrease as your body continues to consume oxygen for its metabolic processes without replenishing it through breathing. This can lead to hypoxia, a condition where there is insufficient oxygen reaching your tissues.
the amount of oxygen entering the circulation from the lungs would decrease.
Breathing faster will only drag more oxygen into the lungs, but to get more oxygen to the muscles it has to be picked up and carried into the body by the blood. So the heart has to pump more too, tho move the oxygen from the lungs to the muscles.
Alveoli are tiny sacs of air located in your lungs. There are millions of them in your lungs, and they fill up with oxygen when you inhale. They greatly increase the surface area of the lungs so that more oxygen can enter your bloodstream.
Oxygen binds to the Fe(II). This causes a shift of the Fe(II) to be in plane with the porphyrin ring and it pulls the His in, which all increase the oxygen affinity.
