Gilrandir vs Immune "System"

[Montmorency]

That is why it is not a separate system. Immunity is the general ability of an organism to resist infection. This function is performed (as you correctly remarked) by sundry organs which belong to OTHER different systems. But there is no separate chain of organs responsible for protection. That is way I maintain that "immunity system" is not a system.



A system is elements plus structure the latter being represented by connections and relations. If some of these are missing it is not a system.

So, as you just stated it there is an interrelated structure, where function is mutually dependent and reactive. Fin.
