In the context of serous membranes, which serous membrane would a surgeon most directly suture if repairing the tissue surrounding the heart?
A
Pleura
B
Peritoneum
C
Pericardium (pericardial serosa)
D
Synovial membrane
Verified step by step guidance1
Understand that serous membranes are thin layers of tissue that line certain internal cavities and cover the organs within these cavities, producing serous fluid to reduce friction.
Identify the specific serous membranes mentioned: Pleura (around the lungs), Peritoneum (lining the abdominal cavity), Pericardium (surrounding the heart), and Synovial membrane (lining joint cavities, not a serous membrane).
Recognize that the heart is enclosed by the pericardium, which is the serous membrane specifically associated with the heart.
Note that if a surgeon is repairing tissue surrounding the heart, they would be working with the pericardium, also called the pericardial serosa.
Conclude that the correct serous membrane to suture in this context is the pericardium, as it directly surrounds the heart.
