Study Notes
Heart Protection and Composition
- Pericardial fluid, present between the double-layered peritoneal membrane covering the heart, reduces friction and allows for smooth movement of the heart.
- The human heart is primarily protected from friction and mechanical shocks by the pericardial fluid and the pericardium, a double-layered membrane that surrounds the heart.
- The heart is composed of cardiac muscle, a type of striated muscle that is capable of involuntary contraction.
Heart Structure
- The human heart is internally divided into four chambers: the left and right atria, and the left and right ventricles.
