The Respiratory System

and Adam Zeelens
Structure and Function
Overview
used all the time
 complex system, and without it we would
not be able to survive
 main function is to supply the blood with
oxygen so the blood can deliver oxygen to
all parts of the body
 respiratory system is the exchange of
gases between you and your environment.

Types of Respiration

two types of
respiration:
 External- the gas
exchange between
lungs and blood
 Internal- the gas
exchange between
blood and body
cells
Parts and Function




Nose- part where air can enter
the body. Prepares the air for
the lungs by clearing out any
dirt or dust.
Mouth- air enters the body
and travels directly to the lungs
Pharynx- tube like space in
the mouth and upper throat
that filters out any dirt or dust
that the nose did not.
Larynx- where the vocal cords
are located, which when air
comes out of the lungs, it
allows one to speak or sing.
The larynx connects the
pharynx to the trachea.
Parts and Function (continued)



Trachea- windpipe
that connects to the
bronchial tubes.
Bronchial tubesbranches that lead
from the trachea to
each lung.
Lungs- fill with air
when breathing.
Diaphragm

Diaphragm- main muscle used while breathing.
It contracts when one inhales and relaxes when
one exhales.
Relation to the Circulatory System

The respiratory system
works with the
circulatory system.
The circulatory system
supplies the body with
oxygen and removes
carbon dioxide. The
circulatory system also
transports the blood
carrying oxygen to the
body cells and picks up
carbon dioxide. Their
relationship keeps us
alive.
Relation to the Excretory System

The respiratory system is related to the
excretory system because it releases
carbon dioxide out of the body through
the nose and mouth. Both the respiratory
system and the excretory system use the
lungs in some way.
Relation to the Muscular System

The respiratory system
is related to the
muscular system
because the
diaphragm is a muscle,
and it allows us to
inhale and exhale.
Without the muscular
system, the
respiratory system
would not be able to
function.
Diseases and Disorders
Lung Cancer
 Cancer
begins in the cells that line
the bronchi tubes
 The cells multiply and form in the
lungs
 The cells eventually form tumors and
spread rapidly
 One of the most life-threatening
cancers

Don’t smoke
Exercise
Eat healthy
Have your home
tested for radon

Surgery
Radiation
Chemotherapy
Emphysema




The lung tissues
needed to support the
lung are destroyed and
can no longer support
the lung
The alveoli disintegrate
and make it difficult for
air to pass out of the
lung
Causes a shortness in
breath
Cannot be reversed

Tuberculosis
Bacterial infection
 Bacterium attack
the lung and then
move on to other
parts of the body
 Highly contagious
 Often Deadly

Tuberculosis (continued)
 Prevention
 Maintain
a health immune system
 Be exposed to fresh air
 Treatment
 Medication
Laryngitis
Swelling of the
larynx
 Vocal cords in the
larynx become
inflamed and cause
irritation
 Typically caused
from a virus
 Your voice will be
raspy

Laryngitis (continued)
Prevention
 Don’t smoke
 Drink lots of water
 Treatment
 Limit using your voice
 Pain relievers
 Cool-mist humidifier

Pleurisy
The lining of your chest becomes inflamed
 Sharp pains when you cough or breathe
 Normally develops as a result of a lung
infection such as tuberculosis

Pleurisy (continued)

 Avoid
lung infections

 Antibiotics

Why the respiratory system?




Breathing is vital to
survive.
One breaths over 20,000
times a day.
The respiratory system
includes your nose, throat,
lungs, voice box, and
windpipe.
You live because of the
respiratory system and its
workings with other body
systems!
Because the respiratory
system is so delicate and
lithe, humans contact
diseases very easily here.
Illnesses: The Common Cough




The cough is the most
common symptom of any
respiratory ailment.
Coughing allows ones
airways to be cleared of
secretions and foreign
bodies.
A cough associated with a
fever or another infection
of the respiratory tract
may be due to bronchitis
or pneumonia.
A wheezing cough be may
present because of
asthma, a common ailment
of the respiratory system.
Illnesses: Bronchitis




Infection of the
bronchioles, tiny airways,
is the reason why people
develop bronchitis.
Young people develop the
bronchitis the easiest
because of their small
airways.
Smoking may increase
ones chances of
developing bronchitis.
One might develop
pneumonia because of
bronchitis.
Illnesses: Bronchitis (continued)



Stuffiness, runny nose, mild cough, and fever are all signs
of bronchitis.
The best way to prevent bronchitis is through hand
washing.
There is no vaccine for bronchitis, however medication is
available.
Illnesses: Sinusitis




Sinusitis occurs when one’s
sinuses become irritated,
causing an infection.
Sinuses are moist air
spaces within one’s facial
bones.
Sinusitis is highly
contractible. Sinusitis
occurs because of a cold or
allergies when nasal
passages become more
swollen.
A dry cough and cold-like
symptoms do occur. Oral
antibiotics may be
prescribed from a doctor.
Additional Illnesses: Asthma

Asthma is a common
condition that
thousands of
Americans develop.
This inflammatory
disease occurs when
thick mucus is
produced by the
bronchioles, making it
harder to breathe.
Wheezing, shortness of
breath, and coughing
do occur.
Additional Illnesses: Pneumonia

Pneumonia is a common respiratory condition of
the lungs. The inflammation of the lungs results
in coughing, a high fever, shaking/chills, and
shortness of breath.
Additional Illnesses: Influenza

Influenza, also known
as the flu, has multiple
symptoms including: a
high fever, coughing,
sore throat, vomiting,
and diarrhea. To
prevent such an illness,
that best medicine is
medicine itself. Shots
are vital to prevent
catching the illness.
Doctors will prescribe
special medication if
one receives the
influenza virus.
Proper Health



To guarantee optimal health, one should not smoke
whatsoever. Smoking, even second hand smoke, increases
the chances of a lung cancer-related death.
Polluted air is also not good for one’s respiratory system.
Exercise, specifically running, jogging, or bicycling
increases the circulation of oxygen.
Proper Safety



In an emergency scenario,
the Heimlich maneuver will
prevent any human being
from choking. The
maneuver forces air out of
the lungs in order to push
out the object that is
blocking the airways.
For unconscious victims,
the abdominal thrust is
used when the victim is
lying on their back.
In any emergency
situation, use the three C’s:
check, call, and care!
