How organ systems support liver cells

[disreputablelabrador]

First off Hi, I have recently began a fast-track A-level course; A-levels in one year.
As a result of this I have developed an interest in Biology, in particular evolutionary biology, although I am not currently taught it.

I am trying to write an essay on Liver cells; I have neared the end of the essay and I wanted to write about how the organ systems support (Digestive, Respiration, Circulation, Nervous and Endocrine systems) help support it. Can anyone enlighten me? I have searched textbooks+internet and can't find anything on it, and I really want to include this in my essay.

what you mean by support? Digestive system provides nutrients, respiratory system provides oxygen and removes carbon dioxide, circulatory system delivers all this stuff incl. hormones.
