Answer
Exam answer
The pericardium is the DOUBLE-LAYERED MEMBRANE that ENCLOSES THE HEART, lying in the thoracic cavity between the two lungs.
Explanation
The question says EXACT location, so give the position precisely — a membrane AROUND the heart, in the thoracic cavity between the lungs.
Its structure explains its function: being double-layered, it encloses a space containing PERICARDIAL FLUID, which reduces friction as the heart beats and cushions it against shock. It also holds the heart in position and prevents it from over-distending.
