two materials exchanged in capillaries

Answer 27

nutrients, dissolved gases, wastes

Question 28

capillary permeability is maximized by a blank wall and low blank

Answer 28

thin, blood pressure

Question 29

permeability in a capillary is thanks to blank across endothelial cells

Answer 29

diffusion

Question 30

diffusion in capillaries can also be through blank between endothelium

Answer 30

gaps

this type of permeability in capillaries that is active transport

Answer 32

vesicular transport with pinocytes

continuous capillaries have many tight blank, blank, and blank

Answer 33

junctions, desmosomes, pinocytes

Question 34

continuous capillaries allow movement by blank diffusion or blank transport

Answer 34

passive, active

Question 35

locations of continuous capillaries

Answer 35

central nervous system, skeletal muscles, lungs

Answer 36

fenestrated

Question 37

two locations of fenestrated capillaries

Answer 37

kidneys, intestines, endocrine glands, choroid plexus

Question 38

capillaries that are specialized for max exchange and have large intercellular gaps and pores

Answer 38

sinusoid capillaries

Question 39

in sinusoid capillaries there is a discontinuous blank membrane which allows cells to blank

Answer 39

basement, enter/exit

Question 40

a network of interconnected capillaries

Answer 40

capillary beds

Question 41

capillary beds are derived from blank

Answer 41

arterioles

Question 42

part of capillary beds that manages blood flow to bed

Answer 42

precapillary sphincters

Question 43

part of capillary beds that are a direct connection through the bed and leads to a thoroughfare channel

Answer 43

metarterioles

Question 44

part of capillary bed that has collateral arteries

Answer 44

anastomoses

Question 45

collateral arteries are two arteries blank

Answer 45

fused

Question 46

in collateral arteries there are twice as much blank that supplies the arteries

Answer 48

arteriovenous anastomosis

Question 49

blood flow may be hindered by posture in blank

Answer 49

arteriovenous anastomosis

Question 50

smallest veins that collect blood from capillaries

Answer 50

venules

Question 51

venules can lack a blank

Answer 51

media

Question 52

venules have a minimal amount of blank sometimes
