Pulmonary

Question 1

safety value

Answer 1

prevents edema formation

Question 2

lymph

Answer 2

by product of filtrate and contains intracellular debris
proteins in lymph because interstitial oncotic pressure

Question 3

dynamic compression

Answer 3

when organism can move limbs and because of movement can compress and displace fluid in one direction
-alternating expansion/ collapsing during ambulation

Question 4

gravity

Answer 4

force for fluid flow

Question 5

lymphatic obstruction

Answer 5

bad!! could cause fluid buildup, increases concentration of RBC

Question 6

compliance equation

Answer 6

C= change volume/ change in pressure

Question 7

V(dot) D

Answer 7

anatomical deadspace
deadspace ventilation important b/c represents airflow without gas exchange
-blood doesn’t get oxygenated, no CO2 exchange
-“parent” branches of bronchi

Question 8

V (dot) A

Answer 8

alveolar ventilation
amount of air that gets to alveoli per unit of time
-branches 17+ of bronchi, where gas exchange occurs

Question 9

alveolar ventilation equation

Answer 9

Va= Ve-Vd

Question 10

V (dot) e

Answer 10

minute ventilation
Ve= RR * TV (how much air comes in and out)

Question 11

rib cage recoil

Answer 11

recoil in 2 directions, inward and outward

Question 12

lung recoil

Answer 12

recoil inward

Question 13

chest wall recoil profile

Answer 13

inward pressure corresponds to lung, happens at high long volume
outward pressure at low lung volume

Question 14

lung compliance equation

Answer 14

change volume/ change in transmural pressure

Question 15

eupovea

Answer 15

normal quiet breathing

Question 16

dyspovea

Answer 16

labored breathing

Question 17

tachypovea

Answer 17

hyperventilating

Question 18

alveolar stability

Answer 18

distendable
recoil
BUT they always want to collapse

Question 19

surfactant

Answer 19

produced by alveolar type II cells, amphipathic
reduce surface tension

Question 20

atelectasis

Answer 20

alveolar collapse, lost stability

Question 21

negative pleural pressure

Answer 21

results from elastic recoil of lungs and chest wall pulling in opposite directions

Question 22

pleural cavity

Answer 22

potential space between ribs and lungs

Question 23

factors that affect diffusion capacity for lung

Answer 23

lung volume
change in PO2 or CO2
V/Q matching
