The air flow of the lungs is as follows...
From the Nasal cavities to the
Pharynx to the
Larynx to the
Trachea to the
Bonchi to the
Bronchioles
Alveoli ...The respiratory gases, oxygen, and carbon dioxide, diffuse across the
Aveolar pulmonary Capillary membrane.
Hope this diaphragm answers your question
Air enters the body when you inhale (Breathe in) air enters through the mouth and into the lungs. and then exhale (Breathe out) carbon dioxide (CO2)
they are alveoli
your lungs have structures called alveoli. The alveoli are surrounded by capillary beds which carry blood. The oxygen enters the alveoli when you inhale. The oxygen then diffuses from high concentration in your alveoli to low concentration the blood in the capillaries surrounding the alveoli.

nose or mouth
trachea
When air enters the empty alveoli in the lungs they become inflated. Now the blood vessels inside the alveoli can take oxygen from this air and put carbon dioxide into it.
Oxygen enters the pulmonary blood in the capillaries of the alveoli -- the air sacs of the lungs.
The Process of the Respiratory System I am a Respiratory Therapist, so this is easy for me. During inspiration, air(gas) enters either through the nose or the mouth. As the air reaches the throat it becomes warmed and humidified and then passes into the trachea. It follows the trachea down into the bronchi then to the bronchioles(smaller versions of the bronchi) then into the alveoli. The alveoli are tiny sacs at the end of the bronchioles that look like clusters of grapes. After the air(gas) enters the alveoli, the oxygen from the air crosses the alveolar-capillary membrane and enters the blood. The blood then carries the oxygen to the organs of the body. During expiration, as the oxygen in the alveoli is entering the blood, carbon dioxide leaves the blood, enters the alveoli and is breathed out.
When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream. During the same process, carbon dioxide is outgassed from the blood to the alveoli When you inhale, air fills the alveoli and oxygen passes from the alveoli through a semipermeable membrane and into the capillaries, leading into the bloodstream.
