Peri stands for around. Cardia stands for heart. So pericardium means around the heart.
pericardium
It is called the pericardium.
Pericardium
The pericardium is the sac surrounding the frog's heart.
The tissue that covers the kidneys is a connective tissue. There are actually three layers of tissue that covers the kidneys, the renal fascia, adipose capsule, and renal capsule.
The pericardium. It is composed of two layers: the fibrous pericardium (the outer layer that is made of tough connective tissue) and the serous pericardium (the inner layer in which serous fluid provides lubrication for the heart to beat with almost no friction).
The serous membrane lines certain cavities in the body. It makes up the pleura, which lines the chest cavity, and the pericardium, which covers the heart.
Fibrous pericardium and serous pericardium. The serous pericardium is made up of an outer parietal layer that is fused to the fibrous pericardium and an inner visceral layer (aka epicardium) that is a layer of the heart wall and adheres tightly to the heart.
The heart is encased in two protective layers. The outer layer -- the pericardium -- covers the heart. It folds in on itself at the aorta forming the epicardium of the heart. Between these layers is a small amount of fluid (10-50 ml) that affords the layers a non-stick surface.
The serous pericardium is a thin, double-layered membrane that covers the heart and consists of the parietal pericardium (outer layer) and visceral pericardium or epicardium (inner layer). The fibrous pericardium is a tough, fibrous layer that surrounds the serous pericardium and helps protect the heart and anchor it within the chest cavity.
They are two names for the same thing
The visceral pericardium, also known as the epicardium, is the innermost layer of the pericardium that directly covers the heart. On top of the visceral pericardium lies the parietal pericardium, which is the outer layer of the pericardial sac. Between these two layers is the pericardial cavity, which contains pericardial fluid that reduces friction during heart movement. Additionally, surrounding the parietal pericardium, there may be fat and connective tissue that provide cushioning and support.
