Transcript of Asthma

Asthma What is Asthma? Asthma is an inflammatory disease of the airways. Cause and Development Specific cause is unknown When does it develop? Symptoms Particular group of people affected/ Lifestyle Choices There are 2 groups where asthma turns out a little bit more prevalent Affected Organ Systems, Organs, Tissues, and Cells Asthma affects mainly the respiratory system. It also affects the circulatory system, nervous system, immune system and excretory system.
Organs affected:
Lungs (Respiratory system)
Heart (Circulatory system)
Brain (Nervous system)
Kidneys (Excretory system)

Tissues affected: Ciliated epithelium tissue. This tissue plays a role in the production of mucous in the lungs. Asthma also affects the muscle tissue surrounding the bronchioles.

Cells affected: Dendritic cells Treatment and Medication Fun Facts Biology Culminating Task •11% of all asthma cases are occupational related.
•There are about 300 million people around the world who have asthma.
•About 3 million Canadians have asthma.
•Every year, about 250 Canadians die from asthma every year.
•Asthma is one of the most chronic disease among the children.
•If one parent has asthma, the risk of their child having asthma is 30%. If both parents have asthma, the risk jumps to about 70%.
•95% of children with asthma still have symptoms of asthma as adults.
•Children who have eczema are at a higher risk for developing asthma later.
Out of all animals, cats and horses are the most likely to develop asthma. Symptoms of asthma are:
Chest tightness
Shortness of breath
These symptoms are triggered by certain things, including:
Dust mites
Viral infections
These symptoms occur because of inflammation of the lining of the airways, and because of the muscles surrounding the airways twitch and tighten. There is no cure for asthma.

However, it can be treated with medication.
There are two main types of medication: Controller medication and Quick relief medication.

The anti-inflammatory medication used are steroids called corticosteroids.
(These are not testosterone replacements- these are anti inflammatory drugs called dexamethasone)
This medication can be taken through an inhaler. The two types of inhalers are aerosol inhalers and dry powder inhalers.
People who can help you with asthma:
A family practitioner
A pediatrician
A pharmacist
A respiratory therapist
An asthma educator Many factors play a part in the development of asthma These include... Genetics Asthma tends to be hereditary. Environmental Factors Exposure to tobacco and living in environments with
dust-mites, animals, pollen and mold Dietary changes Large proportions of processed foods, a higher salt intake and lack of intake of omega 3 fatty acids Bibliography http://health.allrefer.com/health/asthma-info.html

of the airways Occupational
Exposure For adults, asthma can develop because of irritants in their workplace. Such as, chemicals, dust, gases, mold and pollen. -Rarely happens suddenly (within a day)
-Most of the time, cases develop over 6 -12 months It can be inherited Lifestyle choice such as lack of exercise, dietary changes and occupational exposure 10.4% of African-Americans over 18 have asthma Asthma has also been more prevalent in women THANK YOU FOR LISTENING :-)
