What is the serous pericardium?

The

heart is surrounded by two bags of mesothelial cells and protects it from friction during its normal activity. They also reduce the movement of the heart, so that other surfaces are not contacted that could prove harmful. Finally, these SAC prevents the spread of inflammation and infections to the heart. The deeper of these two is known as serous pericardium and is divided into two layers. It is a parietal and visceral layers of serous pericardium.

The parietal layer of serous pericardium lies next to the fibrous pericardium, the outer bag protects the heart. Although these lining are considered separate anatomical entities, they are actually connected. The visceral layer is also associated with the surface, in this case to the outside of the heart.

both layers, parietal and visceral layers, connect to each other in several points. These points are a place where large vessels such as Aorta and Venae cavae are based on the heart. In these places, the tserous pericardium joined the outer layers of these veins. This fusion with different membranesAmi allows pericardium to completely close the heart.

The pericardial cavity is a small space that separates both layers. This cavity in the heart is full of serous fluid of proteins and water. Each layer of serous pericardium produces this fluid called pericardial fluid.

Sometimes trauma or conditions such as tuberculosis can increase the amount of fluid in the pericardial bag. This is known as pericardial discharge and can be life -threatening. Depending on the cause, the pericardial effusion may disperse itself, but it may require surgical intervention. Normally, anywhere from 15 milliliters (ml) to 50 ml of pericardial fluid. The outflow that leads to more than 120 ml of liquid creates excessive pressure on the heart.

If pericardial influenzaid exert pressure on the heart, it can reduce its movement. This can cause several negative effects, including low blood pressure and a decrease in heart rate. AsThe fluid accumulates rapidly, it can affect the severity of this condition.

In the worst scenario, heart tamponade, there is a rapid increase in fluid associated with a rapid decrease in cardiac activity. Eventually it can cause death. Usually, bleeding is the main cause of heart tamponade, but there are other potential causes. These other diseases include tuberculosis, cancer, reaction to drugs, radiation therapy or infection or systemic lupus.
