Shock/Perfusion & gas exchange/Velocity/Fluid Movement through capillaries

Question 1

() shock:
Blood vessels inadequately fill and cannot () blood normally

Answer 1

Circulatory
circulate

Question 2

() shock:
Large-scale blood loss

Answer 2

Hypovolemic

Question 3

() shock:
An inefficient heart cannot sustain adequate circulation

Answer 3

Cardiogenic

Question 4

() shock:
Overwhelming () blood infection

Answer 4

Septic
bacterial

Question 5

() shock:
Severe allergic reaction causing bronchoconstriction and vasodilation

Answer 5

Anaphylactic

Question 6

Tissue (): blood flow through body tissues
Delivery of O2 and nutrients to, and removal ofwastes from, tissue cells

() Muscle
Increased during exercise
()
Constant blood supply
()
Temperature Regulation (vasoconstriction/dilation)
():
Increased considerably during exercise
() System:
Dependent on digestion/need
()
Constant reabsorption/secretion of substances

Answer 6

perfusion
Skeletal
Brain
Skin
GI
Kidney

Question 7

() of flow changes as blood travels through () circulation
Fastest in (), slowest in (),then increases again in ()

Speed is inversely related to totalcross-sectional area
() have largest area, so slowest flow
Slow capillary flow allows adequate time forexchange between blood and tissues

Answer 7

Velocity
systemic
aorta, capillaries, veins
Capillaries

Question 8

Fluid is forced out of capillaries at () end, and most returns to blood at () end
-Extremely important in determining relative fluid () in blood and () space

Answer 8

arterial
venous
volumes
interstitial

Question 9

Direction and amount of fluid flow depend on two opposing forces
() pressures
Pushing force; created by Arterial BP (pushing on the walls, allowing blood to exit)
() osmotic/() pressures
Pulling force; determined mostly by ()

Remaining fluid of interstitial space returned to heart via () system

Answer 9

Hydrostatic
Colloid/oncotic
Albumin
lymphatic

Question 10

(): abnormal increase in amount of interstitial fluid

Increased () pressure: Heart failure, venous blockage, Na+ retention, () failure

Decreased () pressure: () often due to liver and kidney failure
Liver produces ()
Kidney prevents () loss into urine

Answer 10

Edema
hydrostatic, Kidney
osmotic, hypoalbuminemia
albumin
