The Heart Lies Within the ________ Cavity

Question

The heart lies within the ________ cavity.
A) peritoneal
B) pleural
C) orbital
D) dorsal
E) pericardial

Accepted Answer

The heart is located within the pericardial cavity, which is a fluid-filled cavity that is surrounded by the pericardium. The pericardium is a sac-like structure that helps to protect the heart and keep it in place within the chest. The other choices listed (peritoneal, pleural, and orbital cavities) do not contain the heart. The dorsal cavity is a broad term that refers to the posterior (back) side of the body and contains several subdivisions, including the cranial and spinal cavities.
