Respiratory Anatomy Flashcards
Upper airway
Nasopharynx nasal air passage, oralpharynx, mouth, pharynx, epiglottis, larynx
Lower airway
Trachea, alveoli, bronchioles, bronchi, carina,
Upper section of pharynx that connects with nasal caiviry
Nasopharynx
Section of pharynx at back of throat near base of tongue
Oralharynx
3rd section of pharynx
Laryngopharnx
Voice box/vocal cords
Larynx
Protects trachea from food and water
Epiglottis
Leads to lower airway
Trachea
Adams Apple
Thyroid cartilage
Below thyroid cartilage
Cricoid cartilage
Between thyroid and cricoid cartilage
Crock thyroid membrane
Where gas exchange occurs
Alveoli
How many lobes in each king
Right 3 left 2
Breathing muscle
Diaphragm
2 stems supply air to lungs
Bronchi
Smaller and leads from bronchus: bronchi
Bronchioles
Covers each lung
Visceral pleura
Pleurs lines chest cavity
Partiel pleura
Space formed when bloood or air lesk into it
Pleural space
Chest cavity containing heart lungs esophagus and great vessels
Thorax
Gas exchange
Respiration
Movement of sir between lungs and environment
Ventilation
How gas exchange occurs
Diffusion
How body controls breathing
Csf ph drops with too much co2 leading to breathing
Backup based on oxygen levels
Hypoxic drive
Area with little to no gas exchange
Dead space
Amount of air moved by 1 breath
Tidal volume
Biggest breath you can take after a normal breath
Inspiratory reserve volume
Maximum amount of sir you breath out after normal breath
Expiratory reserve volume
Remaining gas inn lungs
Residual volume
Respiratory rate x tidal volume
Minute volume
