pulmonary surfactant (apparnetly this is lecture 8)

Question 1

the respiratory airway?

Answer 1

maybe just draw it

cilia keeps things clean

Question 2

properties of the resp airway?

Answer 2

23 branches from trachea to the alveolar duct

if we looka t cross sectional surface area, the cross section of the trachea is much smaller than the cross section of the bronchiole

the highest resistance to airflow is at the trachea and decreases as you move down

When the air rushes in there is greatest velocity at the trachea and then it decreases — slow laminar

Question 3

describe the flow and area dyanmics

Answer 3

draw it plsssss

Question 4

what are the pores of kohn

Answer 4

these holes that connect adjacent alveoli

Question 5

describe chemical influences on airways

Question 6

autonomic control of airways?

Question 7

cough reflex vs inflation reflex?

Question 8

restrictive lung diseases?

how does it impcat the fev1/fvc

Answer 8

memorise is verbatim

breathign

Question 9

obstructive lung disease?

Question 10

regional differences in ventilation within the lung>

Answer 10

the thing that is different is the intrapleural pressure

you can see that the negativity is greatest at the top of the lung because gravity is pushing the mass of the lung downards and reducing the intrapleural pressure at the bottom of the lung
