The pericardium is a double-layered sac that surrounds the heart externally. It is a double-walled sac-like structure; hence, it is also called the pericardial sac. Pericardium Structure Histologically, the pericardium ... Read more The post Pericardium: Definition, Structure, Functions, Diseases appeared first on Microbe Notes.

Pericardial Function is to protect against myocardial microbial infection, and to protect against mechanical force trauma near the lungs. The parietal pericardium has two layers with a cavity in between with a pericardial fluid. This cavity is the pericardial cavity. There is also a visceral pericardium, which is a membrane lining the heart (superficial epicardium).

The pericardium is a double-walled sac that encloses the heart. Between the visceral and parietal membranes is a space called the pericardial cavity, which contains pericardial fluid. The fluid lubricates the heart and allows beating with little friction.

19.6 Pericardium. The protective layers of the heart include the pericardial sac composed of an outer fibrous pericardium and an inner serous membrane called the parietal layer of serous pericardium. Tightly adhered to the heart is a serous membrane called the visceral layer of serous pericardium. The space between the parietal and visceral layers is called the pericardial cavity, which contains serous fluid produced by both serous membranes

Quick, hold your breath! Now, try to make a giant “oomph” sound without actually letting go your breath. You’ll feel lots of pressure build up inside you as you do this. The Valsalva maneuver is the term given to this action of creating lots of internal pressure by trying to bre

Fluid Analysis Definition of Fluids in various cavities of the body: The fluid is secreted by the serous membranes lining the peritoneum, pleural and pericardial cavities. Literally serous fluid means resembling the serum. This serous fluid is found in the pleural, peritoneal, and pericardial cavities, which will lubricate the opposing parietal and visceral membranes surfaces. Inflammation or infection affecting the cavities causes fluid to accumulate. Serous fluid is t...

The peritoneum lines the interior of the abdominopelvic cavity and is a large slim serous membrane. Peritoneum forms the biggest serous sac of the body and is comprised of a strong layer of elastic ti...

Laparoscopic Peritoneoscopy Laparoscopic peritoneoscopy is the direct inspection of the peritoneal cavity and its contents by means of an endoscopic instrument introduced through the abdominal wall. Laparoscopic surgery has revolutionized the field of surgery and has gradually been replacing many conventional surgical procedures. The procedure is used in gastroenterologic, general surgical, and gynecologic disorders in which a positive diagnosis cannot be established by simpler methods. Its…
