Nasal turbinates (serve to?)

warm, humidify, and filter inspired air

Pharynx (connects the)

nasal passages, mouth, larynx and esophagus (connects these areas?)

Larynx (or voice box provides passage for?)

airway to the trachea

Epiglotts

is a lid like structure at the entrance of the larynx to prevent food from entering the airway

Trachea (windpipe provides support with?)

tubular structure made up of chondral c shaped smooth muscular rings that provide support

Tracheal bifurcation

marks the end of the trachea and beginning of the bronchi

Bronchi

passages that direct air into the lungs (left and right bronchi enter the lungs and branch into smaller & smaller airways that lead to the alveoli)

passage of air (6)

Primary Bronchi - Secondary Bronchi - Teritiary Bronchi - Bronchioles - Alveolar ducts - Alveoli

lungs

organ where gas exchange occurs (left and right)

thorax

located between the neck and the diaphragm. (Visceral pleural; right, left and midiastinum)

diaphragm

is the chief muscle of respiration

arterial blood

bright red due to the oxygen bound to the hemoglobin (being carried to the tissues / away from the heart)

Venous blood

dark/bluish color due to the large amount of CO2 (being carried to the lungs / towards the heart)

Rhinopneumonitis

inflammation of the nose and lungs

Tracheobronchitis

inflammation of the trachea and bronchi

Pneumonia

condition of the lungs (alveolar membranes become thickened and inflamed, infectious)

Asthma

constriction of the airways

Emphysema

breakdown of elastic fibers in alveoli (preventing rebound of air. Results in lung dysfunction)

Pneumothorax

air in the chest cavity

Hemothorax

blood in the chest cavity

Pyothorax

pus in the chest cavity

Hypoxia

condition of below normal Oxygen levels

Hypercapnia

condition of above normal CO2 levels

Dyspnea

difficulty breathing

Apnea

absence of breathing

Cyanosis

condition of blue (cyanotic - not enough oxygen, too much CO2, mucous membrane turn blue)

Pleuritis

inflammation of the pleural cavity (area surrounding the lungs)

Intercostal

space between the ribs

Antitussive

pertaining to being against coughing (cough suppressant)

Nasopharynx

first portion of the pharynx (opening to the back of the nasal chamber & eustachian tubes)

Oropharynx

central portion of the pharynx (opening to the back of the MOUTH, between the roof of the mouth and upper edge of epiglottis)

Laryngopharynx

lower part of the pharynx (opening into the larynx and esophagus)

Upper Respiratory System

Nasal turbinates, Pharynx, Larynx, Trachea, Bronchi

Lower Respiratory System

Lungs, Thorax, Diaphragm

Primary Bronchi, Secondary Bronchi, Teritiary Bronchi. Bronchioles, Alveolar ducts, Alveoli

passage of air (6)

Nasal turbinates, Pharynx, Larynx, Trachea, Bronchi

Upper Respiratory System

Lungs, Thorax, Diaphragm

Lower Respiratory System

nasopharynx, oropharynx, laryngopharynx (parts of the?)

Pharynx (nose, mouth, throat areas?)
