This Mr. Zou...
In the System interface, there was no indication of a disease that Zheng Ren had never seen before, nor was there any random code. Instead, it was clearly marked [Heart Ion Channel Disease].
The bio-membrane ion channel was the channel through which various inorganic ions were transported passively across the membrane. There were two ways for the bio-membrane to transport inorganic ions: passive transport (cis-ion concentration gradient) and active transport (inverse ion concentration gradient).
Generally speaking, ion channels were divided into sodium ion channel disease, potassium ion channel disease, calcium ion channel disease, and chloride ion channel.
