
The function of the respiratory system is to get oxygen to the
rest of the body. The oxygen enters via the nose or mouth,
and then travels through the rest of the respiratory system to
the lungs. It is then transferred to the blood in the capillaries,
where the red blood cells take it throughout the body,
supplying every cell with oxygen. We need this system to stay
alive. All cells go through aerobic respiration, which is the
oxidization of glucose. This is how our cells get enough energy
to function, providing us with healthy tissues, working organs,
functioning organ systems, keeping us alive.

The nose filters and warms the air.
The mouth can assist the passage of air.
The laryngopharynx is located between the hyoid bone, the larynx and the
esophagus, it helps guide both food and air.
The oropharynx is a passageway that connects the back of the mouth and
nose to the esophagus. The top section connects the nasal cavity to the
region behind the soft palate, the middle is for food and air, and the bottom
is just for food.
The nasopharynx communicates with the nasal cavity and provides a
passage way for breathing. Located above the soft palate.
The larynx is a short section of the airway that connects the laryngopharynx
to the trachea. The bottom of your larynx contains special structures called
vocal folds, which allow you to talk and make noise.
The trachea provides a clear path for air to reach the lungs. The cilia
on the epithelial cells helps trap contaminants like dust, to stop them
reaching the lungs.
 The diaphragm is underneath the lungs and is attached to the
spine. It is the major muscle of respiration. When we breathe, it
presses itself downward until it is flat, while the muscles in the ribs pull
the ribs up, allowing the lungs to expand fully.
 The lungs are two spongy organs that are located above the
diaphragm. They are each surrounded by a pleural membrane that
gives them room to expand, as well as negative pressure that allows
them to fill slowly with air as they relax.


When we breathe in, we use the diaphragm. The diaphragm
flattens out so the lungs have room to expand to allow air in.
When breathing in, the air goes through the nose or mouth,
down the windpipe, into bronchi tubes, and then air sacs
called alveoli.
The alveoli help to clean out blood cells as they transfer
oxygen to the blood. Then the waste gas is breathed out.
That gas is called carbon dioxide.
From the lungs, blood returns back into the heart and is
pumped to the rest of the body carrying oxygen with it.


The circulatory system
We breathe in order to get oxygen to our red blood cells.
When the lungs fill with oxygen, the oxygen is transferred to
the blood in the capillaries inside our lungs. This is called
external respiration. The oxygen is then carried by the blood
cells to tissues all over the body. This is called internal
respiration.

The digestive system also connects to the respiratory system
because some of the passageways that are used for
inhalation and exhalation are also passageways for food
before it reaches the rest of the digestive system. For
example: the mouth is used for both chewing (digestive) and
breathing (respiratory). Likewise, the laryngopharynx is a
passageway for both air and food.

Organ systems like the respiratory system are made up of lots of
organs working together. Organs are made up of different types of
tissues, and each type of tissue is made up of cells with the same
structure and function. For example, in the respiratory system, one
organ is the diaphragm. The diaphragm is made up of many types
of tissues, one of which is muscle tissue. Muscle tissue is made up of
muscle cells.

one disease that can affect the respiratory system is a disease
called emphysema. This is caused when you smoke. What happens
is it destroys the tissue in the persons lungs, but the tissues can not be
regenerated. Once you have emphysema, doctors say it would be
best and breath pure oxygen only to survive.

Another diseases is pneumonia . The effect of pneumonia is it
causes your lungs to fill with a fluid or a pus. When you have
pneumonia you have a lack or breathing, or in other causes
you cant take in as much oxygen because of the fluid/pus.
Pneumonia is caused by Bactria, viruses, fungi or parasites.
To not catch the disease emphysemas, you would simply quit
or not smoke at all, if you already have the dieses, your
doctor can give you special puffers. There is no real way to
prevent pneumonia unless your doctor gives you
medication. The disease can affect the young and healthy,
but people over 50 years of age have greater risk of
catching pneumonia

Lung infected with pneumonia


To maintain a healthy respiratory system, you can either not smoke,
work out so you are giving you’re the whole respiratory a work out
and if you have asthma, use your puffers daily or when you need it.
Another example that most people do when they live in a big city is
breath in carbon dioxide from vehicles/buses or smog

Where do respiratory therapists work and what do they do?
The respiratory therapist mostly works in hospitals and home
care settings. A respiratory therapist is an indispensable part
of the health care team, both in hospital and in home care
settings.
Pulmonologists are physicians who specialize in evaluating
and treating the lungs.

-Did you know that the highest record “sneeze speed "is 165 kph?
Breathing is so vital to life that it happens automatically. Each day,
you breathe in about 20,000 times. By the time that you're 70, you'll
have taken at least 600 billion breathes.
If the inside of your lungs was spread out flat, they would occupy
roughly the same size of a tennis court
Did you know that our right lung is slightly bigger then our left lung
because the right lung has 3 lobes and the left lung only have 2
We lose half a liter of water a day through breathing. This is the
water vapor we see when we breathe onto glass
