Chapter 23: Respiration Flashcards
Functions of the respiratory system
Gas exchange, moves air in and out of the lung, Protects passageways from toxins, makes it sound, gives you your olfactory system
Nose nasal cavity pharynx
Upper respiratory system: clean air warms air moistens air
Larynx trachea bronchi and bronchioles alveoli
Lower respiratory system
Respiratory tract: runs from the entrance to the bronchioles
Conducting portion
Respitory retract: runs from bronchioles to alveoli
Respiratory portion
Lines the respiratory tract
Respiratory mucosa
Secretes mucus for lining
Lamina propina
Extensions that move mucus upward filters air
Cilia
Nostrils
Nares
Division of the nostrils
Septum
Store mucus to keep areas moist
Paranasal sinuses
Upper jaw
Maxillary
Forehead
Frontal
Behind eyes
Ethmoidal
Temples
Sphenoidal
Create sense of smell
Olfactory receptors
Area above the soft and hard palate
Nasopharynx
Soft palate to base of tongue
Oropharynx
Hyoid bone to epiglottis
Laryngopharynx
Made up of hyaline cartilage
Larynx
Opening in larynx
Glottis
Upper front plate
Thyroid cartilage
Lower front plate
Cricoid cartilage
Flap that prevents food from entering trachea
Epiglottis
Left lung
Two loves
Right lung
Three lobes
Area where primary bronchi, blood vessels and nerves enter the lungs
Hilus
Top of the lung
Apex
Bottom of the lung
Base
Primary bronchi and all of the branches off of it
Bronchial tree
The functional unit of the lung
Alveoli
Primary bronchi and all of the branches off of it
Bronchial tree
Have cartilage part of bronchial tree
Tertiary bronchi
Part of bronchial tree: bronchioles
No cartilage
Part of bronchial tree contain smooth muscles
Terminal bronchioles
broncoconstriction smaller
Parasympathetic
Broncodilation bigger
Sympathetic
Small segments of the long in the blood vessels that supply them
Pulmonary lobules
Tissue that covers the surface of the long
Visceral pleura
Remove dust particles from alveoli
Alveolar macrophages
