Dynamics of the Vascular System
fascia of the skeletal muscle is tact
or
removed (Fig.
7.2.2).
It
is
interesting to note that the capillary distensibility is retained even when
the fascia is intact. However, the greater distensibility when fascia is
removed case suggests that skeletal muscle contraction can influence
capillary
distensibility.
The
consequence is a reduction
of
the
distensibility during contraction.
