Draw a circuit of the path of current through the human body for a person touching a voltage source with both hands who has both feet at the same potential as the negative terminal of the voltage source


Physiological raection: current flowing in (Rt)
Barely Perceptible: 3-5 mA
Extreme Pain: 35-50 mA
Muscle paralysis: 50-70 mA
Heart stoppage: 500 mA

First of all electricity follows "every" path, each path with different amplitude.
Your listing of current in a human and it's effect is a bit off,
5 to 7 mA is enough to cause a heart attack...

In US GFCI is rated at 6mA while in UK RCD is rated at various ratings from 10 to 500mA but in homes they use 30mA rated ones.
