1. The respiratory system

2. Major structures

Epiglottis epiglott/o
Pharynx pharyng/o
Larynx blaring /o
Trachea trache/o
Brocnchi bronch/o, bronchi/o

3. Functions of the respiratory system:
Bring oxygen rich air into the body for delivery to the blood cell.
Expel waste products (carbon dioxide and water).
Produce the air flow through the larynx that makes speech possible.

4. Structure of the respiratory system
It is consists of
A. The upper respiratory tract, that consists of
Nose, which contains
nasal cavity
nasal septum
Mucous membrane (mucus, cilia, olfactory receptors).

5. 2- Mouth which contain
Tooth
Tongue
Gum
3-Pharynx which contain
Nasopharynx
Oropharynx
laryngopharynx

6. 4- Epiglottis which contain
orophaynx and laryngopharynx
Epiglottis
5-Larynx which contain
voice box
Larynex
glottis

7. 6- Trachea which contain
Windpipe or airway
Mucous membrane lining with cilia
Smooth muscle with
c-shaped cartilage rings
Divided into tow branches
No gaseous exchange

9. B. The lower respiratory tract consist of
Bronchial tree
Lungs

10. Medical specialties related to the respiratory system
A pulmonologist :
Is a physician who specializes in diagnosis and treating disease.
A respiratory therapist (RT) :
Provides treatment of breathing problems.

11. Medical terms related to the respiratory system
Tonsils : Lymphatic tissue in the back of the mouth near the throat.
Breathing: a process by which air enters and leaves the body.
Inhalation: (or inspiration) is the flow of air into the body.
Exhalation (or expiration) is the flow of the respiratory current out of the body.

Accumulation of blood in the plural cavity
hemoptisis

14. The common terms related to respiratory system
Pneumonia
Inflammation of lungs the air sacs fill with pus and other liquid
Tachypnea
Rapid rate of respiration more than 20 breath per minute
Bradypnea
low rate of respiration less than 10 breath per minute
Apnea
Absence of respiration
Dyspnea
Difficult of breathing
Cyanosis
Bluish discoloration of skin caused by lack of oxygen
Bronchscopy
Visual examination of the bronchi

15. LABORATORY TESTS AND DIAGNOSTIC PROCEDURES
Bronchoscopy: Visual examination of the bronchial tubes with an endoscope. Computed tomography (CT) scan: Cross-sectional x-ray images of the chest.
Laryngoscopy: Visual examination of the larynx via the placement of a flexible tube (laryngoscope) through the nose or mouth and into the larynx.
Magnetic resonance imaging (MRI): Magnetic waves and radiofrequency waves create images of the chest in three planes of the body.
Pulmonary angiography: X-ray images are taken of the blood vessels in the lung after the injection of contrast material into a blood vessel. A blockage, such as a
pulmonary embolism, can be located with this procedure.
