C
– exchange between blood and tissues; D – support; E – repair.
2. Each of the following statements concerning the loose connective tissue is true,
EXCEPT:
A
– contains relatively fewer fibres, but more amorphous ground substance; B – its fibres
are arranged in parallel bundles; C
– contains various cells; D – is located under epithelia
and around blood vessels; E
– is mainly specialized for the transport function.

4. Each of the following statements concerning the macrophages is true, EXCEPT:
A
– arise from blood monocytes; B – contain numerous primary and secondary lysosomes;
C

shape; D
– have acentric nuclei; E – contain a lot of rER.
7. Each of the following statements concerning the white adipose cells is true,
EXCEPT:
A
– have a thin rim of cytoplasm; B – contain numerous mitochondria; C – possess
flattened nuclei; D
