Question

How can you appreciate the protection of heart with pericardial membranes and pericardial fluid?​

Answer 1

Answer:

It prevents your heart from stretching too much and overfilling with blood. It lubricates your heart to prevent friction with the tissues around it as it beats. It protects your heart from any infections that might spread from nearby organs like the lungs.

Answer 2

PERICARDIAL FLUID AND MEMBRANES:

First of all, let's learn a few facts about pericardium and it's fluid:

• Pericardium is a multi-layered membrane covering the heart. The outer membrane is called the parietal pericardium, the inner membrane is called the visceral pericardium.

• Now, the the fluid present in between the parietal pericardium and the visceral pericardium is known as the pericardial fluid.

How do they protect heart?

• First of all, the pericardial fluid acts as a shock absorber and prevents any trauma to the heart.

• Secondly, the pericardial fluid also prevents wear and tear between the pericardial membranes (during beating of heat) by lubrication of the membranes.

• In absence/decrease of pericardial fluid, a characteristics sound known as the "pericardial rub" can be heard. It indicates the pathologic condition.

• The pericardium fixes the heart in a particular place within the mediastinum in the chest cavity.

• It also prevents overstretching of the heart chambers (due to excessive filling of blood).
