70
Q

In ______, the liver attempts to repair its damaged cells by replacing them with bands of connective tissue, which is NON-FUNCTIONAL. The connective tissue divides the liver into clumps, rerouting many veins and capillaries. BLOOD FLOW IN THE LIVER IS DISRUPTED. Poor food intake leads to deficiencies.
