, Order the steps of pulmonary ventilation, with the first step on the top and
the last step on the bottom.
The diaphragm contracts.
Air moves from the area of higher pressure outside the body to the area of lower pressure inside
the lungs.
Oxygen moves into the pulmonary capillaries and carbon dioxide moves out of the pulmonary
capillaries.
The diaphragm relaxes.
Air moves from the area of higher pressure inside the lungs to the area of lower pressure
outside of the body.

Exercise 1
What is the most prevalent structure in the lung tissue? Explain the
prevalence of this structure in terms of lung function.
The most noticeable structures in the lung tissue are the alveoli, which are tiny air sacs
found throughout the lungs. They are present in such large numbers because they are
responsible for the essential process of gas exchange. This is where oxygen moves from
the air into the bloodstream, while carbon dioxide leaves the blood to be exhaled. Having
millions of these tiny air sacs creates an enormous surface area, making gas exchange
much more efficient. This design allows the lungs to supply the body with the oxygen it
needs while removing carbon dioxide, helping the respiratory system function effectively
and keeping the body's cells supplied with oxygen.
