Question

In humans, the _________ fluid present in pericardium protects the heart from injuries.
A) Pleural
B) Mucosal
C) Pericardial
D) None of the above

Answer 1

Hint:The membrane encompassing the heart is called pericardium. It is a double membrane structure. The external layer is fibrous and the internal layer is serous.

Complete answer:
The membrane encompassing the heart is called pericardium. The external layer is fibrous and the internal layer is serous. The serous layer secretes the liquid called pericardial liquid that shields the heart from wounds. The pericardial fluid decreases friction in the pericardium by greasing up the epicardial surface permitting the layers to coast over one another with every heartbeat.

Additional Information:
It is discovered that the fluid consists of a high concentration of lactate dehydrogenase (LDH),lymphocytes and proteins. In a grown-up adult there is up to 50 ml of clear, straw-shaded fluid.

A pericardial effusion is the presence of unreasonable pericardial liquid; this can be affirmed utilizing an echocardiogram. Little effusion is not really hazardous and is normally brought about by contamination like HIV or can happen after heart surgery procedure. Enormous and quickly gathering emissions may cause cardiovascular tamponade, a perilous entanglement that squeezes the heart keeping the ventricles from filling accurately.

Pericardiocentesis is a methodology used to eliminate the pericardial fluid from the pericardial space. It is performed utilizing a needle and under the direction of an ultrasound. It can be utilized to diminish pressure from pericardial effusions or for analytic purposes, demonstrating the reason for anomalies, for example, Cancer, Cardiac hole, cardiac injury, Congestive cardiovascular breakdown.

Therefore, the correct answer is option (C) Pericardial.

Note:Pleural fluid is present between the pleural membranes around the lungs. Mucosal fluid is secreted by mucosa that lines the inner body cavity.Normally there is between 10–50 ml of pericardial fluid present in the heart.
