How does the body react to electicution?

Answer 1

Psychological
The perception of electric shock can be different depending on the voltage, duration, current, path taken, frequency, etc. Current entering the hand has a threshold of perception of about 5 to 10 mA (milliampere) for DC and about 1 to 10 mA for AC at 60 Hz. Shock perception declines with increasing frequency, ultimately disappearing at frequencies above 15-20 kHz.


Physiological
Burns - Tissue heating due to resistance can cause extensive and deep burns. High-voltage (> 500 to 1000 V) shocks tend to cause internal burns due to the large energy (which is proportional to the square of the voltage) available from the source. Damage due to current is through tissue heating. In some cases 16 volts might be fatal to a human being when the electricity passes through organs such as heart.

Ventricular fibrillation - A low-voltage (110 to 220 V), 50 or 60-Hz AC current travelling through the chest for a fraction of a second may induce ventricular fibrillation at currents as low as 60mA. With DC, 300 to 500 mA is required. If the current has a direct pathway to the heart (e.g., via a cardiac catheter or other electrodes), a much lower current of less than 1 mA, (AC or DC) can cause fibrillation. Fibrillations are usually lethal because all the heart muscle cells move independently. Above 200mA, muscle contractions are so strong that the heart muscles cannot move at all.

Neurological effects - Current can cause interference with nervous control, especially over the heart and lungs.

When the current path is through the head, it appears that, with sufficient current, loss of consciousness almost always occurs swiftly. (This is borne out by some limited self-experimentation by early designers of the electric chair and by research from the field of animal husbandry, where electric stunning has been extensively studied).

Arc-flash hazards - Over 80% of all injuries and fatalities caused by electrical incidents are not caused by electric shock, but by the intense heat, light, and pressure wave (blast) caused by electrical faults. The arc-flash in an electrical fault produces the same type of light radiation from which electric welders protect themselves using face shields with dark glass, heavy leather gloves, and full-coverage clothing. The heat produced may cause severe burns, especially on unprotected flesh. The blast produced by vaporizing metallic components can break bones and irreparably damage internal organs. The degree of hazard present at a particular location can be determined by a detailed analysis of the electrical system, and appropriate protection worn if the electrical work must be performed with the electricity on. Worker safety standards in the USA require, though, that the electricity be turned off before work is performed unless a greater hazard will result from turning the power off.

Answer 2

It doesn't react as such.
Your muscles react to normal levels of electrical pulses normally, and with the increased electrical activity in your body, all your muscles contract.

Depending on the level of current, and the duration of the electrocution, this would have several consequences. Most of all it would interfere with the natural electrical pulses in your heart, which could cause it to stop (and hence induce death). Also the muscle spasms have been so severe in people that they have broken bones in their body. For longer periods it basically cooks flesh.

When people are put to death by electrocution, paradoxically the anus relaxes and they loose control of their bowels and subsequently defecate themselves.

For minor periods of time and low current, there is no certainty what electeocution will do to a person. Some may have no injuries, some may have moderate injuries. Basically the longer the exposure and the higher the current, the more likely there will be severe injuries, and ultimately death.

Interesting, yes. Disgusting, most definitely.

Answer 3

Electrocution (spelled with an "r") has two classes
of effects:

1: It causes the nervous system to be completely unable
to transmit signals while it is happening - which is necessary
if you want your heart to beat, etc.

2: It causes cell damage as various chemical reactions
stop and others start. The cells most likely to die causing
the whole body to die are ... nerve cells. Yeah, you can
kill muscle, skin and vascular cells, but the nerve cells
(particularly in the spine and head) are the weak points
of the system (electrically speaking).

It doesn't help that the nerve cells are the longest in
the body so they conduct electricity particularly well.

In any case, while it is happening, all sorts of "false"
signals are sent to the various muscles (causing the
"shake, rattle and roll"), but the key thing is that the
heart has lost its signal to beat and has probably
stopped.

Clearly whether or not it starts again will determine the
fate of the victim. No heart, no oxygen. No oxygen
in the brain, everything shuts down.
