Anatomy QIV

Respiratory System

exchange of gases between the blood and air at the lung alveoli external respiration
gas exchange between the blood and the tissue cells internal respiration
name the 10 structures in order which air passes through once it is inhaled 1) nose, 2) nasal cavity, 3) paranasal sinuses, 4) pharynx, 5) larynx, 6) trachea, 7) bronchi, 8) bronchioles, 9) lungs, 10) alveoli
transports the air, includes all structures of the respiratory system up to the respiratory bronchioles conducting zone
where does the conducting zone terminate? the terminal bronchioles
the site of gas exchange, the end part of the respiratory tree, starts at the respiratory bronchioles respiratory zone
three functions of the nose moistens, warms, and filters air
external nares nostrils
external nares are divided by the nasal septum
posterior nasres also called choanae
regions of the pharynx from superior to inferior nasopharynx, oropharynx, laryngopharynx
lateral walls of the nasal cavity formed by the (3 bones) superior concha, middle concha, inferior concha
floor of the nasal cavity formed by (2 bones) palatine and maxillary bones
floor of the nasal cavity formed by (2 bones) palatine and maxillary bones
roof of the nasal cavity formed by (3 bones) ethmoid, frontal, sphenoid
a funnel-shaped passageway that connects the nasal cavity and mouth pharynx
the portion of the pharynx that is for air only nasopharynx
opening from the pharynx to the larynx glottis
three of the nine pieces of cartilage that constitute the larynx thyroid, cricoid, and laryngeal prominence
another name for the laryngeal prominence Adam's apple
the guardian of the airways epiglottis
an internal ridge that marks the bifurcation of the bronchi carina
windpipe trachea
posterior part of the cartilage rings that make up the trachea is formed by the ____ muscle trachealis
how many divisions of the bronchial tree are there? 23
the main right and left bronchial division is classified as ___ bronchi primary
the second division of the bronchi, how many right and left? two names for this division 3 right, 2 left-secondary/lobar bronchi
third division of bronchi, how many in each lung? two names for this division 10 in each lung-teriary/segmental bronchi
little bronchi, less than 1 mm in diameter bronchioles
last part of the conducting zone, less than .5 mm in diameter terminal bronchioles
bronchioles which branch from terminal bronchioles, lead to the alveolar ducts respiratory bronchioles
gas exchange across the alveoli and blood capillaries is accomplished by simple diffusion
a double-layered sac surrounding each lung pleurae
portion of the lungs deep to the ribs costal surface
superior tip of each lung apex
inferior portion of lung which sits atop the diaphragm (two names) base, diaphragmatic surface
medial surface of the lung mediastinal surface
opening on each lung for bronchial tubes and any vessels/nerves hilus
space on the left lung which accomodates for the heart cardiac notch
how many lobes of the left lung? 2
how many lobes of the right lung? 3
how many fissures in the left lung? 1
name of the fissure in the left lung oblique fissure
how many fissures in the right lung? 2
names of the fissures of the right lung-which is the more superior, and which is more inferior? horizontal/transverse (more superior), oblique (inferior)
how many segments per lung? 10
the smallest division of the lung tissue seen with the naked eye lobules
the supporting tissue surrounding each lung structure, "supporting mattress" stroma
