Answer 1

Endocardium - Innermost Epithelial Layer
Myocardium - Muscular Middle Layer
Pericardium - Visceral (Epicardium) Layer
Pericardium - Pericardial Cavity
Pericardium - Parietal (Epicardium) Layer
Pericardium - Fibrous Pericardial Layer

Endocardium - Innermost Epithelial Layer - in contact with blood in the chambers of the heart.

Myocardium - Muscular Middle Layer - contractile tissue thicker in the ventricles and thinner in the atria

Pericardium - Visceral (Epicardium) Layer - encapsulates the the myocardium

Pericardium - Pericardial Cavity - filled with pericardial fluid to reduce friction during heart movement

Pericardium - Parietal (Epicardium) Layer - encloses the pericardial cavity
