Final answer:
The bacterial infection of the heart can cause inflammation of the heart layers, which are the endocardium, myocardium, and pericardium.
Step-by-step explanation:
The bacterial infection of the heart can cause inflammation of the heart layers. The correct order of the heart layers, from innermost to outermost, is: endocardium, myocardium, pericardium. The endocardium is the innermost layer that lines the muscles and valves of the heart. The myocardium is the middle layer, consisting of heart muscle cells. Finally, the pericardium is the outermost layer that surrounds and protects the heart.
