Default Anatomy question for you

A 35-year-old woman is brought to the emergency department 30 minutes after sustaining blunt trauma to the chest in a motor vehicle collision. Her blood pressure is 90/50 mm Hg and her pulse is 105/min. A CT scan of the chest shows a tear in one of the pulmonary veins at the point at which it enters the heart. Into which of the following spaces is this patient most likely hemorrhaging?

A. Between the epicardium and the parietal pericardium
B. Between the fibrous pericardium and the parietal pleura
C. Between the myocardium and the epicardium
D. Between the parietal pericardium and the fibrous pericardium
E. Between the parietal pleura and the visceral pleura

The pericardial sac has two layers...fibrous and serous
Serous layer is further divided into parietal and visceral layer...

The parietal layer is fused with the fibrous layer
The visceral layer is part of d epicardium

So d potential space is actually between
1) parietal layer (which fused to and inseperable from d fibrous layer and
2) d visceral( wch is part of epicardium)

Answer is A

A
Usually heart covered by 3 memberanes
Visceral, parietal and fibrous
If blood accumulates in pericardial space between visceral n parietal then it can't expand outward because fibrous is fused with the parietal layer and fibrous layer in non.stretchable so heart cant expand rather compress inward interfering with diastole so blood pressure will decreased..

My answer is AA

Because there will be hemopericardium. Blood in pericardial sac i.e, between Viceral(epicardium) and parietal pericardium.

Thanks
