The Guide to How These Fabulous Things Work
The trachea is a five-inch long tube that connects the larynx to the bronchi. It allows air to pass through the throat.
Thyroid and Cricoid Cartilage
This cartilage is a strong connection
between the larynx and the thyroid
cartilage. It's primary role is opening and
shutting the air passageways.
The thyroid cartilage, also known as the
Adam's Apple, is the largest of the cartilage
in the larynx. This cartilage grows as you
do, so your voice will grow deeper,
especially in men.
The right lung consists of three distinct
There are two fissures that separate the three lobes. The one that separates the superior lobe from the middle lobe is called the
right oblique fissure
separates the middle and inferior lobes.
The left lung consists of two lobes and one fissure.
The lobes are the
lobes, and are separated by the
left oblique fissure
One special fact about the left lung
is that it is considerably smaller
than its right counterpart. The reason for this is because two thirds of the heart is on the left side of the body. Therefore, the left lung has to contain a
, which surrounds the apex of the heart.
Fissures and Notches
are two pieces of the trachea that split off between the two lungs. As the
bronchi enter the lungs, they split off into
bronchi, and so on until they spread out in-between both lobes.
Alveoli are the
functional units of the lungs. These provide the ability for the exchange between blood in the capillaries and the air in the lungs.
Keeping Your Lungs Healthy
Regular exercise can strengthen the lungs.
Keeping a healthy weight will lessen the workload of your lungs.
Be careful when around poisonous gases, such as carbon monoxide. Respirators may help if you really need to be near a gas like that, such as during an emergency.
Don't smoke, as it leads to lung cancer, emphysema, and bronchitis. Various other cancers and diseases also may come as a result.
Destroying Your Lungs
Smoke cigarettes. This will fill your lungs with tar and lead to lung cancer. In addition to being terrible for your lungs, this will affect your quality of life. Your chances of living satisfyingly for a long time will decrease.
Inhale toxins and other drugs to further damage your body and your precious lungs.
Purposely become infected with diseases/ viruses to further ruin your lungs, and, more importantly, your life expectancy.
Become overweight and refuse to exercise or eat healthily. This will cause your lungs to have less room to expand, causing less and less oxygen to get into your blood.
