What is the main function of the pericardium?
The pericardium acts as mechanical protection for the heart and big vessels, and a lubrication to reduce friction between the heart and the surrounding structures. A very important role in all aspects of pericardial functions is played by mesothelial cells.
What is the function of the pericardial cavity quizlet?
What is the function of the pericardium? Keeps the heart contained in the chest cavity. Prevents the heart from over expanding when blood volume increases.

What are the four major heart chambers?
The heart has four chambers: two atria and two ventricles.
- The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
- The right ventricle pumps the oxygen-poor blood to the lungs.
- The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
Which chamber of the heart has the thickest myocardium?
left ventricle
The myocardium is thickest in the left ventricle, as this chamber must create substantial pressure to pump blood into the aorta and throughout systemic circulation.
Can the pericardium heal?
Pericarditis is often mild and goes away on its own. Some cases, if not treated, can lead to chronic pericarditis and serious problems that affect your heart. It can take weeks or months to recover from pericarditis.
What happens if you remove the pericardium?
When this happens, the heart can’t stretch properly as it beats. This can prevent the heart from filling up with as much blood as it needs. The lack of blood can cause increased pressure in the heart, a condition called constrictive pericarditis. Cutting this sac away allows the heart to fill normally again.

How long can you live after a Pericardiectomy?
The longest survival was 214 months. The actuarial survival rates were 91 %, 85 % and 81 % at 1, 5 and 10 years, respectively. Mean duration of the pericardiectomy operation was 156.4 ± 45.7. Cardiopulmonary bypass utilization was not high (12.8 %).
