Block 4 - Respiratory System Flashcards
humans have blank respiration
external
mucosa has blank connective tissue and many blank
loose (lamina propria), lymphocytes
submucosa has blank ct and blank lymphocytes
denser, fewer
mucosal epithelium of the respiratory tract
ciliated simple columnar
arms of ciliary tubules to help move mucus… the motor of cilia
dynein
other cells of respiratory tract
goblet cells, pulmonary brush cell (could be sensory), small granule cell (like enteroendocrine
glands in nose that secrete mucus
bowman’s glands
sinus under pituitary gland
sphenoid
aka adenoids
pharnygeal tonsil
biggest cartilage of larynx that makes up adams apple
thyroid
cartilages of larynx
ok
epiglottis is made up of blank cartilage
elastic
two vocal folds
false, true
rings of trachea are incomplete blank
posteriorly
posteriorly there is a blank which is a smooth muscle connecting the ring of cartilage to each other
trachealis muscle
bronchus has a blank epithelium in light microscopy
convoluted
bronchiole vs bronchus
bronchiole has fewer goblet cells
bronchiole has more smooth muscle
bronchiole is blank when resting
constricted (parasympathetic)
bronciole is blank when running
dilated (sympathetic)
last part of conducting system of respiratory system
terminal bronchiole
two cells of terminal bronchiole
clara cell (surfactant like substance), ciliated columnar cells
stuff beyond terminal bronchioles
alveoli
number of goblet cells, height of epithelium, amount of cartilage all blank as respiratory tubules decrease in size
decrease
a bronchiole lacks both blank and blank unlike bronchus
cartilage, glands
most common infection of the body
respiratory
lung is divided most deeply into these…. round things surrounded by black stuff
lobule of miller
lobule of miller has the blank structures of the lungs like alveoli
smallest
blackish lymph vessel things surrounding lobules of miller
dirt/pigment
cells of bronchiole that dont have cilia
clara cells
more alveoli come off at blank than blank
alveolar sack, alveolar duct
type 1 pneumocyte is very blank and has long blank
flat, processes
type 2 pneumocytes are more blank than type 1
numerous
type 1 pneumocytes are covered with blank from type 2 pneumocytes
surfactant
type 1 pneumocytes resemble blank
squamous epithelium
little things formed during respiratory distress in a premature baby before lung collapse
hyaline membrane
there are often blank in an alveolar septum or wall
macrophages
macrophages in lungs are aka blank
dust cells
dark things in alveoli… has more of this than any other part of respiratory system
elastic fibers
two types of circulation in lungs
systemic (supplying lung tissue), pulmonary (oxygenation)
arteries supplying lung structures
bronchial arteries
blank is always running with a bronchiole
pulmonary artery
blank is around the outside of the lobule of miller
pulmonary vein
pulmonary veins are surrounded by blank
alveoli
bronchiole has a lot of blank and no blank
smooth muscle, glands
c shaped cartilage makes it obvious that its blank
trachea
blank to blank has no goblet cells
terminal bronchioles, alveoli
