Talk:Pericardial fluid

This article is confusing. The pericardium consists of two main layers - the fibrous and the serosal layers. The serosal layer is then divided into parietal and visceral layers. The pericardial fluid lies between the layers of the serosal pericardium, not between the fibrous and serosal layers, according to Gray's anatomy 40th edition. The article confuses these layers.
