But Viruses, diseases and antibiotics are able to pass through the tissues to the different quarters. In side each quarter there are thousands of tiny cells that are called  ``alveoli``. Its takes thousands of those cells just to make one drop of milk. For the cow to produce milk the alveoli meed energy, this energy comes from nutrient rich blood flowing through the udder.
