The respiratory system provides protection against some microorganism by preventing their entry into the body and by removing them from respiratory surfaces.

Larynx
commonly called the voice box, is an organ in the neck of amphibians, reptiles, and mammals (including humans) involved in breathing, sound production, and protecting the trachea against food aspiration.

Bronchitis
Bronchitis is an acute inflammation of the air passages within the lungs. It occurs when the trachea (windpipe) and the large and small bronchi (airways) within the lungs become inflamed because of infection or irritation from other causes.

Influenza
Influenza is a viral infection that affects mainly the nose, throat, bronchi and, occasionally, lungs. Infection usually lasts for about a week, and is characterized by sudden onset of high fever, aching muscles, headache and severe malaise, non-productive cough, sore throat and rhinitis.

How do we take care of our respiratory system?
1. Avoid smoking 2.do breathing exercise daily 3. Get the habit of filling the lungs with
good air during the day 4.Avoid places with very dirty air, such as
traffic jams 5. Drink plenty of water. 6. Avoid prolonged exposure to very cold
weather.
