Hello, good morning... all my friends...   ƪ( ˇ▼ˇ)ʃ

Ok. I want to explain about  " Human Respiratory System "

The first, breathing in, the air is filtered by nose strill, the air is filtered by nose hairs, after that the air go to pharynx, then to larynx, and then to trachea, after that the air through to bronchi, then to bronchioles, and then to alveolar.

After this inflation brings air from outside the body into the lungs.
So, oxygen in the air moves from the lungs through blood vessels to the heart, which pumps the oxygen-rich blood to all parts of the body. 
Oxygen then moves from the bloodstream into cells,
which completes the first phase of respiration.

After oxygen pumps to all parts,
of then oxygen go to diaphragm through blood stream and 
in the diaphragm the oxygen exchange be CO₂. In the cells, 
oxygen is used in a separate energy producing, process called cellular respiration,
which produces carbon dioxide as a byproduct.

Finally, in the lungs, breathing out or exhalation removes carbon dioxide from the body, thus completing the respiration cycle.
