Respiratory System Flashcards
What us the structural classification of the respiratory system
Upper - nasal cavity to larynx, lower - larynx to lungs
What do the lungs look like
conical shape, rounded apex, broader concave base
What so the lobes look like
the superior middle and inferior on the right, and superior and inferior on left. There is an oblique fissure and horizontal fissure
What lung is the oblique fissure on
both
what lung is the horizontl fissure on
right
What is the nasopharynx, oropharynx and laryngopharynx
the throat
What is the respiratory epithelia
Warms and humidifies the air. It alo traps and cleans the air (simple columnar)
What is the goblet cells
secrete mucus
Doe epithelial tissue get simpler or more complex as it goes down
simpler - pseudostratifies to simple squameous
Why is the shape of the nasal cavity retarded
because surface area
What is the thyrois cartillage
the adams apple
What does the larynx do,
change the pitch of voice
What is the lower respiratory tract
cartilage, smooth muscle fiber
What goes behind the lungs in the cartilagenous ring
oesophagus, makes the tract c shaped
what is the splitting part called
primary bronchi
What are the levels of bronchi
primary bronchi, secondary bronchi, tertiary bronchi, small bronchi, bronchioles, terminal bronchioles
What is the secondary go to
lobes
what does the tertiary bronchi go to
segments
What are the alveoli duct and sacs
the duct is a alveolus, and a group is a sac
What are the green bits
expansion of the alveolus
What do alveoli do
they exchange gas to blood vessels, they do simple squameous
What are pneumocytes
gas exchange boys
What does gas exchange occur
alveoli and capillary blood vessels
What are the the pleural membranes
Visceral and parietal, there is also the pleural cavity
What happens when a collapsed lung…
The air bubbles exist in the membrane
What is boyles law
volume is inverse to pressure
What is inspiration
When diaphragm congtracts and thoracic cavity increases
What is the expiration
diaphragm relaxes, lungs expands
What other muscles force the breath
accessory muscles
What happens with pulmonary arteries
CO2 goes out
what happens with pulmonary veins
O2 goes in
WHAT IS SUPERIOR
Kim jong un jk, pulmonary veins
Do bronchi have pulmonary arteries/veins
yes
