Re: Blood Electrification current density in the artery

You say that human muscle has over 600 times the resistance of blood? Do you know HOW it has been measured?

Don’t forget, that human tissue consists of cells suspended in an aqueous medium. As a consequence, the electrical conductivity of a tissue is inhomogeneous on a microscopic scale. The „dry” muscle fibers have far greater resistance than blood, which is fluid.

On a macroscopic scale the conductivity of a tissue can be considered to be homogeneous, and this conductivity is called the effective conductivity. The human body consists of approx. 70% water. The blood is only small part of it.

Now, body fluids contain much of electrolytes, their conductance is in fact 2x greater than blood!

The average resistivity of normal human blood (40% hematocrit) is between 148 to 176 omega cm. Watch this: most tissues, namely skeletal (171 omega cm) and cardiac (175 omega cm) muscle, kidney (211 omega cm), liver (342 omega cm), lung (157 omega cm) etc.

You took inhomogeneous values and misinterpreted them – this indroduced your error.

Have you ever heard of Bioelectrical Impedance Analysis (BIA)? There are devices which measure all about water in human body, like total body water (TBW), intra-cellular body water (ICW), extra-cellular body water
(ECW), body cell mass (BCM) etc. etc. You hold electrodes in your hands and that’s basically how measurement is done. If all the current (100%) went thru the blood, how all the above could be measured?
