  Solution
The aid that relaxation of muscle give to venous flow
Note- the muscle are under relax postion causing compression of venous flow ( blue color demostrate vein that carry venous blood) causing contraction of the venous supply in between the relaxing muscles.
This may slow the blood volume coming out of the relaxed muscle due to narrowing of the venous blood vessel.
