The respiratory system consists of respiratory tract and lungs. The respiratory tract consists of: nose, posterior nasal apertures, throat, larynx, trachea, two main bronchi and bronchioli.
The role of the respiratory tract is to heat, humidify and, what is the most important, clean the air coming to the lungs.
The respiratory tract is the site of a large range of disorders for three reasons:
– it is exposed to the environment and therefore may be affected by inhaled organisms, dusts, or gases;
– it possesses a large network of capillaries through which the entire output of the heart has to pass, which means that diseases that affect the small blood vessels are likely to affect the lung; and
– it can be the site of “sensitivity” or allergic phenomena that may profoundly affect function.
For more information about the anatomy of the human respiratory system and the process of respiration, see human respiratory system.
Many times, people are genetically more likely to get respiratory conditions, but your work place or environmental exposures could also play a big role.
Some advices to avoid respiratory system illnesses:
Elimination of exposure to tobacco smoke
Smoking is the cause of a number of diseases among which circulatory system diseases are the most common ones. If you are already suffering from circulatory system diseases, then smoking may even cause death. Hence, it is best to avoid it completely. If chemicals from smokes reach your blood, it can cause several diseases.
For information and support in quitting smoking you can visit www.quit.ie the HSE Quit website which aims to encourage smokers to quit.

It is one of the method of preventing primary asthma in children.
Avoiding exposure to polluted atmospheric air/smog
According to many studies, the contaminants present in the air we breathe irritate the respiratory system and lead to its chronic inflammation. This, combined with all kinds of pollen that cause allergy, leads to asthma.
Avoiding stress can significantly improve your overall health. Too many concerns and worries can jeopardize your health and can cause several health problems such as stroke, angina and possibly even ruin your heart health.
Exercise and workout
One way to keep you your circulatory and respiratory systems healthy is to exercise regularly. Exercise makes your lungs and heart stronger and makes you breathe in more oxygen. Any activities that get you moving are good for your circulatory and respiratory systems. You should try to get at least thirty minutes of exercise three days a week.
A well based diet combining several health nutrients can help improve body functions and the respiratory system. If you’re hoping to start dieting, include foods that contain high levels of protein. Foods containing protein include lean meats, turkey, fish, soy, eggs, low-fat dairy products, whole grains, fruits and vegetables.
