missing choices:
A) continuous capillaries, with no intercellular cleftsÂ
B) sinusoid capillaries, with incomplete basement membrane
C) fenestrated capillaries, with thin diaphragms made of extracellular glycoproteins
D) metarterioles leading directly to thoroughfare cannels
In the brain the fluid that filters out of capillaries is highly regulated. you would expect to see A.) CONTINUOUS CAPILLARIES, WITH NO INTERCELLULAR CLEFTSÂ feeding the brain.
