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
No, not all the air you inhale reaches your alveoli. Some of it remains in your airways (such as your trachea and bronchi) and is exhaled back out. The air that does reach your alveoli is where the exchange of oxygen and carbon dioxide takes place.
The air sacs in your body, known as alveoli, hold oxygen-rich air that is essential for respiration. When you inhale, oxygen from the air enters the alveoli and diffuses into the bloodstream, while carbon dioxide from the blood is expelled into the alveoli to be exhaled. This exchange of gases is crucial for providing oxygen to your body's cells and removing waste gases.
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
Oxygen enters the blood in the alveoli of the lungs
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
Oxygen is the primary gas absorbed into the blood through the lungs during respiration. When we inhale, oxygen from the air enters the alveoli, small air sacs in the lungs, where it diffuses across the alveolar membrane into the bloodstream. Additionally, carbon dioxide, a waste product of metabolism, is released from the blood into the alveoli for exhalation.
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.
trachea, which then branches into the bronchi and bronchioles, ultimately reaching the alveoli in the lungs. This is where the exchange of oxygen and carbon dioxide with the bloodstream takes place.
Alveoli are tiny air sacs in the lungs where gas exchange occurs, surrounded by a network of capillaries. When we inhale, oxygen from the air enters the alveoli and diffuses across their thin walls into the adjacent capillaries, where it binds to hemoglobin in red blood cells. This process allows oxygen to enter the bloodstream while carbon dioxide moves from the blood into the alveoli to be exhaled. Thus, alveoli and capillaries work together to facilitate the efficient transfer of oxygen into the bloodstream.
