Why does the human body conduct electricity? Why does the human body conduct electricity

When a person touches a live wire, the current will pass through the human body, which is called an electric shock. When an electric current passes through the human body, it can cause varying degrees of damage to the human body and internal tissues. There are two types of injuries: electric shock and electric injury.

Electric shock refers to the relatively serious damage to internal tissues caused by electric current passing through the human body. If the electric current continues to pass through the human body, the heart, respiratory function and nervous system of the electrocuted person will be injured, and the heart activity will stop as death. Electrical injury refers to the localized damage caused by an electric current to the outside of the human body.

Electrical injuries generally include arc burns, electric imprints and molten metal infiltration (called metallization). In short, when a person is electrocuted, due to the current passing through the human body and the occurrence of electric arcs, the human body is often burned, and in severe cases, death is caused. <>

Many people know that the human body also conducts electricity. Why? This is to find the cause in the internal tissues of the human body.

There is an electric current in the human body, so there are electrolytes such as sodium, potassium, calcium, etc., and the electrolytes are in the human body fluids. The human body contains a large amount of blood, lymph and cerebrospinal fluid, which is mainly composed of water, and every cell in the human body is filled with water, in which various electrolytes are dissolved, all of which constitute human body fluids. Bodily fluids are present in the human body and account for a very large amount, accounting for 70% of body weight.

When the electrolyte is dissolved in the human body fluids, it forms charged ions, and these ions move directionally in the body fluids under the action of an external electric field, forming an electric current, and the human body also has conductivity and becomes a conductor. Since the human body can conduct electricity, we must pay attention to the prevention of lightning accidents and electric shock accidents to avoid misfortune. <>

Because the human body contains a lot of water, minerals, electrolytes, so the human body will conduct electricity, the conductivity of the human body is also related to the degree of dryness and wetness, rough and dry resistance can reach tens of thousands of ohms, delicate and moist, the resistance can be reduced to less than 800 ohms, the degree of conductivity of the human body is related to voltage and human resistance, the current endured by the human body in a short time is about 30 milliampes, and the general human body perceives the current to be about 1 milliampere

The human body can conduct electricity. Because human tissues contain a lot of water and mineral electrolytes, people conduct electricity.

Yes, you can. Because the human body contains a lot of sweat and blood, these liquids can conduct electricity.

Why does the human body conduct electricity

Our bodies are not like metal, which conducts electricity easily, but also unlike wood, which is almost not energized at all. Because although our ability to conduct electricity is very poor, when we have just washed our hands or are sweating profusely, our ability to conduct electricity will increase.

Our human body is wrapped in **, and inside the body are all kinds of muscles, internal organs, and bones. These tissues are all soaked in the blood, lymph and other liquids in the human body, and these liquids are like ordinary tap water, which can conduct electricity, so once the electricity passes the ** level, it will flow throughout the body and travel unimpeded.

In fact, if it is pure water without any impurities, it will not be able to pass through the current. In general, ordinary water can conduct electricity because it contains some impurities.

Looking at the fluid in our body, it also contains a lot of metal ions, such as sodium, iron and other ions, which have a considerable degree of electrical conductivity.

The conductivity of various tissues and organs in the human body will vary depending on the amount of water they contain, for example, the brain and heart have a lot of water content and strong conductivity; Bones have less water content, less electrical conductivity.

The human body contains a large amount of blood, lymph and cerebrospinal fluid, which are mainly composed of water, which dissolves various electrolytes, such as calcium, sodium, potassium and other trace elements. These trace elements often exist in the form of charged ions in body fluids, and move in a directional way to form an electric current, so the human body has electrical conductivity and is prone to electric shock.

The maximum voltage that the human body can withstand is 36 volts, and if the number exceeds 36 volts, the person may suffer damage or even death due to excessive current.

Summary. Electrification of the human body is harmful to the human body, but the size of the harm mainly depends on the size of the current, and the damage caused to the human body by different current intensity is not the same.

Is the human body good or bad at conducting electricity?

Electrification of the human body is harmful to the human body, but the size of the harm mainly depends on the size of the current, and the damage caused to the human body by different current intensity is not the same.

When the current is 10mA, it will cause serious damage to various systems of the body, and even endanger life.

So the human body does not conduct electricity well.

This will be harmful to one's own body, the conduction is mostly direct current, and the human body cells themselves have electric ions, and other external currents, which will affect the change of charge and increase the destruction of cell function, and then a long-term will also cause a decline in physical fitness, so the human body conduction is not good.
