According to the starling law, parasympathetic effects on cardiac rate and contractility include decreasing the rate of contraction and increasing the filling time resulting in a stronger contraction.

Answer: This cell will not respond quickly to what work do they need to do.

Homeostasis may not be maintained properly.
