Respiratory System
Amazing Machinery
Importance
of Oxygen
Amazing Machinery
The respiratory system provides a way of exchanging
nutrients and waste between our blood and the surrounding air. It's
primary function is to provide the blood with oxygen from the surrounding
atmosphere, and to release the waste product carbon dioxide back
into the atmosphere. Our bodies have also developed other functions
that take advantage of this airflow. The air is drawn past thousands
of smelling receptors within our nose, which inform us whether food
is fit to eat or not. During ancient times these receptors also
told us whether or not a mate was receptive and warned us of predators
or prey.

Our voice box harnesses the air
in order to communicate with others, whether we can see them or
not. Through evolution our respiratory passageway has developed
many practical features. It comes with a humidifier, heater, filter,
self-cleaning mechanism and an emergency-flushing feature. The moist
mucosal lining within the passageway from the nose to the branches
within the lungs humidifies the incoming air, protecting our blood
from dehydration and protecting the respiratory tissues from desiccation
(drying out). The distance the air must travel before reaching the
blood allows it to be warmed up to body temperature, protecting
the blood and thus the rest of the body from heat loss. The mucus
within the long passageway filters the air by trapping unwanted
debris and thus protecting the tiny spaces within the lungs from
blockage, where exchange must take place. The cilia within the passageway
constantly cleans the respiratory tract, sending debris to the pharynx
to be swallowed and eventually excreted, or to be coughed up and
spit from the mouth. Sneezing also acts to powerfully eject unwanted
foreign material within the air. All these characteristics are only
enough to sustain the vital respiratory system as long as you don't
abuse it.
The Importance
of Oxygen
Within minutes, cells of the body experience irreparable damage,
if not supplied with oxygen. ATP is a molecule used to provide energy
for tons of different biochemical reactions required for your cells
to function. It is the main "energy currency" of the body. Using
oxygen, the cells can create 36 molecules of ATP for every single
molecule of glucose, by a process known as aerobic metabolism. This
is the body's primary way for obtaining usable energy and is
only possible when supplied with oxygen. Without enough oxygen,
the body uses a short-term source for energy called anaerobic metabolism.
During this process, only 2 molecules of ATP are produced for every
one molecule of glucose. This process is obviously extremely less
efficient at producing energy than aerobic metabolism. In addition,
anaerobic metabolism produces a waste product called lactic acid,
which slows down biochemical reactions, thus limiting the time allowable
for anaerobic metabolism to occur. After a short burst of energy
supplied by anaerobic metabolism, oxygen is needed to recover, and
to convert the lactic acid into a less harmful substance. So, without
oxygen your body can only use anaerobic metabolism, resulting in
less energy, and can only produce this energy for a short period
of time. Within seconds, lactic acid buildup begins to interfere
with normal cell function. Within minutes, the resulting lack of
energy and the interference with biochemical reactions causes cell
damage.

Naturally Free From Asthma Report
This 48-page report explains how you can free yourself from asthma, sinus and allergies using a safe, natural, fast-working, drug-free treatment. Results from clinical trials show that severe asthmatics are able to totally eliminate their need for asthma treatment drugs (or reduce it by over 90%) using this method. The report offers…
Taking care of your respiratory system means taking care of your lungs for one thing...
22%
of all cancers and 33% of all cancer deaths in men are due to lung
cancer.
Smokers are...
- 23 times more likely to develop lung cancer
if male.
- 13 times more likely to develop lung cancer
if female.
- 19 times more likely to develop emphysema.
If you want your lungs to provide you with life
instead of death, never smoke. If you're a guy, smoking will
increase your chance of lung cancer 23 times. If you're a girl
smoking will make you 13 times more likely to develop lung cancer.
Lung cancer isn't fun unless you enjoy coughing up blood, chest
pains and suffocating slowly. The same symptoms occur with emphysema,
which destroys the lungs elasticity requiring the victim to gasp
for breath day after day after day. Oh by the way, if you smoke,
you're 19 times more likely to develop emphysema.
Secondary smoke is actually more toxic than
inhaled smoke because much of it is unfiltered. If your family members
smoke while driving you to school, ask them to refrain for the short
period of time that you're in the car. If they continue anyway,
open the window. When your friends ask if you mind, be honest with
them and say yes. If they disregard your request, they don't
respect your feelings. If you must, go to the hardware store and
buy a filter to place over your nose and mouth. If this doesn't
make your point, maybe taping photographs of lung cancer on your
chest might do the job. However you choose to deal with live-in
smokers, there is no reason you must suffer for their addiction.
If you live under polluted city air, exercising
in the early morning or evening will decrease traffic related pollutants.
If you have a cough for over 2 weeks, especially
if phlegm is produced, visit a doctor.
Exercise! Cardiovascular exercise is the most
effective exercise for maintaining healthy lungs. Swimming is highly
recommended to increase lung capacity. Regular exercise trains muscles
to use oxygen more efficiently so you don't get so easily winded.
Many researchers believe (due to animal studies)
that lack of oxygen plays a major role in causing cells to become
malignant or cancerous. So breathe deeply! Breathing deeply also
improves the circulation of your lymph and thus helps to cleanse
your body of toxins.
You can do breathing exercises to further your
lymph circulation, give you more energy and to make you more resistant
to cancer. Here's how: 10 deep breaths 3 times a day. For each
deep breath, inhale, hold your breath and exhale at a time ratio
of 1:4:2. This means you can inhale for 7 seconds, hold it for 28
seconds, and exhale for 14 seconds. Or if this is stressful, try
inhaling 4 seconds, holding 16 and exhaling 8. As long as you keep
the 1:4:2 ratio your breaths should cleanse your body and provide
you with more energy.
Get your annual influenza shot. A nasty bout
with the flu can result in lasting lung damage and if it progresses
to pneumonia it can even be fatal. In addition to your shots, make
sure you get plenty of Vitamin C, you reduce your stress through
exercise and relaxation, and you get 8 hours of sleep per night
whenever possible, in order to reduce your susceptibility to colds
and other respiratory infections.
- You breathe enough air throughout your lifetime
to fill 10 million balloons.
- The air from a sneeze travels at almost
100mph.
- Humans breathe 20 times per minute.
- Only 1/5 of the air you breathe is oxygen.
- One cigarette shortens your life by 14 minutes.
- Yawning can be the result of a lack of oxygen.
