Answer 4

supporting outer matrix, anchors to neighbouring tissues

Question 5

capillaries and sinusoids

Answer 5

exchange vessels

Question 6

non fenestrated

Answer 6

no gaps between endothelial cells

diffusion occurs through the cells

Question 7

fenestrated

Answer 7

small pores between the walls of neighbouring endothelial cells
greater fluid movement

Question 8

sinusoids

Answer 8

larger irregular lumen
creates turbulence
gaps between neighbouring endothelial cells and basal laminar
gaps large enough for some cells to move between
