Introduction and Anatomy of Lungs, Airways and Blood Supply Flashcards
Features of Nose
The cilia and mucus trap particles and warm and moisten the air that passes through
Features of Pharynx
Air from your nose moves down this structure
Features of Epiglottis
A small flap of tissue that folds over and prevents food entering your trachea
Features of Larynx
This is the voice box that contains your vocal cords and vibrate to produce sound
Features of Trachea
From pharynx air moves down to the trachea which is made up of stiff hyaline cartilage
Features of Bronchus
Air moves from the trachea to branch off in these structures
Features of Lung
Maim organ of respiration
Upper Respiratory Tract
Pharynx, Nose, Larynx, Tongue, Oesophagus
Lower Respiratory Tract
Trachea, Bronchi, Lung, Diaphragm
Features of the Right Lung
Superior Lobe Middle Lobe Inferior Lobe Horizontal Fissure Oblique Fissure
Features of the Left Lung
Superior Lobe
Inferior Lobe
Oblique Fissure
How many times does each bronchus branch to terminate at the alveoli
22
Bronchioles
No cartilage, patency is maintained by physical forces in the thorax
Alveoli
Type 1 Pneumocytes: gas exchange
Type 2 Pneumocytes: produces surfactant
Alveolar macrophages ingest foreign material that reaches the alveoli
Functions of the respiratory system
Gas exchange
Acid-Base balance
Protection from Infection
Communication via speech control of air
