- The pericardium (G. around the heart) is a double-walled fibroserous sac that encloses the heart (G. kardia) and the roots of the great vessels.
- It is located in the middle mediastinum, posterior to the body of the sternum and the 2nd to 6th coastal cartilages, and anterior to T5 to T8 vertebrae.
- The pericardium consists of two parts: (1) a strong external layer composed of tough fibrous tissue, called the fibrous pericardium, and (2) an internal double-layered sac composed of a transparent membrane called the serous pericardium.

∙ 14y agoThe visceral pericardium is the inner layer of the pericardium, the double layered sac surrounding the heart. The visceral pericardium lies directly against the outside of the myocardium (heart muscle).

∙ 12y agothis is the fluid present in between heart and pericardium and prevent fricition between them.

What fluid reduces friction in the heart?
The pericardial fluid
What secretes pericardial fluid?
Pericardial fluid is a fluid that is secreted by the serous membrane on the pericardious sac on the outside of the heart.
What is normal pericardial fluid?
Normal pericardial fluid is clear to straw colored. During pathological examination normal pericardial fluid does not contain blood, cancer cells, or bacteria.
What fills the pericardial sac?
The pericardial sac contains the heart and pericardial fluid which serves to protect the heart. The fluid is secreted by the serous visceral pericardium and is similar to the cerebral spinal fluid that cushions the brain.
What is a pericardial infarction?
fluid on the heart
What is pericardial aspiration?
aspiration of pericardial fluid for diagnostic purposes or treating cardiac tamponade
What is the medical term meaning abnormal collection of fluid in the pericardial sac?
Pericardial effusion.
Will pericardial fluid run out?
If your serous visceral pericardium some how stops producing the lubricant then theorically yes it is possible. Though it is more probably that there will be an over production of pericardial fluid which is know as a pericardial effusion.
What fuild fills the pericardial sac?
serous fluid
What does water do to your heart?
Water around the heart is also called a pericardial effusion. The pericardium is a sac that surrounds the heart. If this sac fills with fluid, a pericardial effusion, then the ability of the heart to contract normally is compromised.
Surface of the heart?
The pericardial fluid acts as a lubricant and reduces friction between the opposing surfaces as the heart beats (contacts). The pericardial fluid is secreted by the pericardial membranes.
How much fluid does the pericardial sac hold normally?
Normally there is approx 25mL of fluid in the pericardial sac. As little as 100-200mL of rapidly accumulating fluid can cause problems with the normal function of the heart
