RESPIRATORY SYSTEM

Brings oxygen into the body. Gets rid of carbon dioxide.

Functions

Gas Exchange

The respiratory system allows oxygen from the air to enter the blood and carbon dioxide to leave the blood and enter the air.

Voice production

Air movement pass the vocal chords makes sound and speech possible.

Olfaction

The sensation of smell

Innate immunity

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

Parts of respiratory

system Nose Nasal cavity Pharynx

Larynx Trachea Bronchi Lungs

Upper Respiratory Tract

Lower Respiratory Tract

Nose

 is the protruding part of the face. that bears the nostrils.

Nasal Cavity

The nasal cavity is a large air filled space above and behind the nose in the middle of the face.

Pharnyx

 is the part of the throat situated immediately inferior to (below) the mouth and nasal cavity, and superior to the esophagus and larynx.

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.

Trachea

 a tube or system of tubes that carries air.

Bronchi

 is a passage of airway in the respiratory tract that conducts air into the lungs.

Lungs

The lungs are a pair of spongy, air-filled organs located on either side of the chest

Common infectious disease of the respiratory system

Common cold

The common cold is a viral infectious disease of theupper respiratory tract which affects primarily the nose. Symptoms include coughing, sore throat, runny nose, and fever which usually resolve in seven to ten day

Pneumonia

Pneumonia is a lung infection that can be caused by different types of microorganisms, including bacteria, viruses, and fungi.

Symptoms of pneumonia include cough with sputum production, fever, and sharp chest pain on inspiration (breathing in).

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.

7. Eat plenty of fruits and vegetables that are rich in vitamin C everyday.

8. get sufficient sleep and rest 9. Inhale and exhale properly. Always

maintain a good posture.
