air can enter through either the nose or the mouth and it travels down the trachea until it reaches the lungs, once the air is in the lungs, the alveolar sacs take it the oxygen and replace it with carbon dioxide, which we then exhale
The flowchart of the path of the process is as follows:
Nostrils of the Nose → Nasopharynx → Oral Pharynx → Glottis → Trachea → Lungs (Right and Left Bronchi → Bronchioles → Alveoli)
The oxygen is used by the mitochondria of eukaryotic cells in the process that is known as cellular respiration. During cellular respiration, oxygen gas and the sugar glucose are converted into water, carbon dioxide gas, and an energy source called ATP (adenosine triphosphate).
Between the alveoli sacs and small capillaries of the circulatory system, the oxygen exchange occurs, by which oxygen is delivered from the lungs to the bloodstream. Then, the oxygen attaches to the hemoglobin of red blood cells, which after that transport to cells such as located in muscles. The mitochondria of eukaryotic cells uses oxygen called cellular respiration, during which the sugar glucose are converted into water, carbon dioxide gas, and ATP.
