Respiratory System
By Stephen Koehler
2 functions of respiratory system
 Take
in oxygen
 Breathe out carbon dioxide
Respiration
 Respiration
is a process that takes place
in your cells.
 It gives you energy.
 Oxygen is essential for respiration to take
place.
 Respiration could not happen without the
digestive and circulatory system
Path of Air
 Air
goes into the nose------- down into the
pharynx-------- to the trachea-----air
passes into the bronchi tubes------ to the
lungs
Respiratory System
 The
two lungs are the main organs of the
respiratory system.
 Lungs are made up of tiny structures
called alveoli
 Alveoli is a hollow sack
How you Breathe
 Breathing
is controlled by the diaphragm
 Diaphragm are the muscles right below
the lungs
 When a person breathes in diaphragm
contracts or gets shorter/space inside the
chest gets bigger
 When a person breathes out the
diaphragm relaxes/space inside the chest
gets smaller
Smoking and your Health
 Nicotine
is a chemical in tobacco that
speeds up the heart and raises blood
pressure
 Tar is a dark, sticky material that forms
from burning tobacco
 When people smoke Tar sticks to the tiny
hairs that lines the respiratory system
 Tar in the lungs is a cause of cancer
Health Problems and Smoking

Smoking can cause people to develop chronic bronchitis,
emphysema, lung cancer, and atherosclerosis
 Bronchitis is a disease of the breathing passages. The
passages get narrow and clogged with mucus
 Emphysema is a disease of the lungs
 The tissues of the lungs are destroyed and so it makes it
harder for Gas exchange to take place
 Lung Cancer is cancer of the lungs. Lumps of cancer
tissue, or tumors, grow out of control and it makes it hard
for gas exchange to take place

Atherosclerosis is when chemicals in tobacco smoke get
into the blood.
Fatty tissues develop from chemicals in smoke and it
makes it hard for gas exchange to take place
Tobacco use such as Chewing tobacco and Dip or Snuff
can cause mouth cancer, throat cancer, gum disease
and tooth loss
The chemicals in Chewing tobacco, Dip or snuff cause
the gums to decay and bleed
The chemicals in tobacco can cause cancer which are
lumps that can be found in the throat or mouth.
