basically, the viruses have a special compounds on their surface that binds ONLY to a receptor on the liver cell, and its not found on any other cell. so that's is how a virus for hepatitis C for instance ONLY infects the liver. its frankly a receptor ligand interaction

What are the large fixed phagocytes in the lining of the hepatic sinusoids called?

Are viruses made up of tissues?
No, tissues are made up of cells and viruses are not even cells.
Are viruses smaller than eukaryotic cells?
Yes, viruses are smaller than eukaryotic cells.
Why do you classify viruses as obligatory intracellular parasite?
Viruses need living cells to produce more viruses. They are obliged to use living cells.
When body cells are attacked by viruses they produce what?
INTERFERON is a substance produced by body cells when they are attacked by viruses.
Are viruses made out of a cell or cells?
well viruses are caused by bacteria and bacteria are cells. so yes
Are viruses made of a cell or cells?
