Interesting in their intial statement on the most important function of the liver they not only use the coloquial confusing, tho accurate term, of filter but equate its eliminative function as the most important, and only relegate to a later mention the processing/manufacturing and et al which to my thought would be more primary to basic function.
Also interesting is that if in ut all functions of the liver would be optimised because the incoming blood would already be high in needed items,then we should be able to project and find that ect ect ect.
