(Created page with "'''Staining''': HE '''Organ''': Heart '''Description''': The slide is from a cross-section of the heart. Five layers can be distinguished. From the bottom layer to the top layer: # The bottom layer is the myocardium. It’s normal. # The second layer is the visceral pericardium. It’s also normal. # The middle layer contains fibrosis # The second-from-the-top layer is pale, has some neutrophils and contains some loose connective tissue # The top layer is very eosino...")
