Nov 2, 2023 · The pericardial cavity is a potential space between the opposing layers of the serous pericardium's parietal and visceral layer. This cavity has a fluid layer, that allows the heart to pulsate and move without friction. The fluid also serves to diminish surface tension and provide lubrication.

The pericardium is one of several serous membranous cavities in the human body; it is comprised of two closely connected structures, including: 1. The fibrous pericardium:A tough external layer comprised of fibrous connective tissue. 2. The serous pericardium:A thin layer that coats the internal surface of the fibrous pericardium. Between the fibro...
The pericardium has several very important roles pertaining to the heart, including: 1. Keeps the heart positioned in the mediastinum via its attachment to the sternum, the diaphragm, and the outer layer of the great vessels (called the tunica adventitia). 2. Prevents the heart from overfilling as the firm, fibrous layer of the pericardium is not a...
There are several common medical conditions associated with the pericardium, including: 1. Pericarditis: An inflammation of the pericardium that may be caused by an infection, trauma, a myocardial infarction (heart attack), or other causes (including idiopathic or unknown causes). Pericarditiscan be acute (sudden and severe) or chronic (long-term)....
Many tests are available that can help doctors diagnose conditions of the pericardium, including: 1. Pericardial fluid analysis: Sometimes the fluid of the pericardium is removed using a procedure called pericardiocentesis.The fluid is examined for signs of disease. The test is performed by aspirating fluid from the sac with a large needle. An ultr...
Jul 19, 2022 · Where is the pericardium located? Your pericardium is located in your chest, where it surrounds your heart. Your heart is located in the front of your chest, slightly to the left of your breastbone (sternum). If you have dextrocardia, your heart is slightly to the right of your breastbone. What are the layers of the pericardium?
Aug 28, 2020 · Found between the outer and inner serous layers is the pericardial cavity, which contains a small amount of lubricating serous fluid. The serous fluid serves to minimize the friction generated by the heart as it contracts. Overview of the layers of the heart wall.

Jul 30, 2022 · The heart resides within the pericardial sac and is located in the mediastinal space within the thoracic cavity. The pericardial sac consists of two fused layers: an outer fibrous capsule and an inner parietal pericardium lined with a serous membrane.

Nov 3, 2023 · Between the layers is the pericardial cavity, a potential space filled with 15 - 50 milliliters of serous pericardial fluid. Pericardial fluid is secreted by pericardial cells, and it is this fluid that reduces friction between the parietal and visceral layer during heart contractions.
