The friction produced would result in damage to the lungs and organs
(i
...
The heart) in order to prevent this the lungs are surrounded by the pleural membrane
which protects the lungs from creating friction with other organs
...
When a breath is inhaled oxygen makes its way to the lungs and passes through the bronchus
(plural: bronchi) and bronchioles, these are lined with smooth muscle which controls the
passage of air
...
The oxygen is diffused in the lungs until it reaches the alveoli (plural: alveolus)
...
The circular
nature of the alveoli means they have more surface area meaning as previously mentioned
they are efficient at gas exchange

The above diagram shows de-oxygenated blood from the heart passing by an alveoli and
becoming oxygenated this is done following the steps listed below:

...
Oxygen passes into the air spaces of the alveolus
...
After dissolving into the lining the oxygen is diffused through the alveolus lining and then
through the lining of the capillaries
...
The outside of the lungs are soft, in contrast the inside of the lungs are spongy with hard patches
due to the bronchioles and bronchi
...
When
exhaling the diaphragm moves upwards as the size of the chest cavity decreases, this is
because pressure within the cavity increases and forces the air out
...
Trachea - The trachea is lined with cartilage supports that are C-shaped
...
Peak Flow:
Peak flow is the speed of the air flow when you exhale, this is used to measure how well your
lungs work based on the speed and force with which you exhale air
