Explanation:

Answer 2

➤ Answer :-

⟶ The layers of the heart are :-

→ Myocardium

→ Epicardium

→ Endocardium

________________________________

⟶ Myocardium :-

• Myocardium is one of three types of vertebrate muscles, with the other two being skeletal and smooth muscles.
• It is an involuntary, striated muscle that constitutes the main tissue of the walls of the heart.

⟶ Epicardium :-

• When the visceral layer of serous pericardium comes into contact with heart it is known as the epicardium.
• The epicardium is the layer immediately outside of the heart muscle proper.
• The epicardium is largely made of connective tissue and functions as a protective layer.

⟶ Endocardium :-

• The endocardium is the innermost layer of tissue that lines the chambers of the heart.
• Its cells are embryologically and biologically similar to the endothelial cells that line blood vessels.
• The endocardium also provides protection to the valves and heart chambers.
