The pericardium.
It is composed of two layers: the fibrous pericardium (the outer layer that is made of tough connective tissue) and the serous pericardium (the inner layer in which serous fluid provides lubrication for the heart to beat with almost no friction).
The fibrous sac of tissue that encloses the heart is the pericardium. It provides protection for the heart.
The ribs, and the Sternum.

The area is known as a foci of necrotic tissue, eventually turning into fibrosed (scar) tissue. The process by which this occurs is tissue ischaemia (where not enough oxygen is supplied to the heart tissue to meet its requirements).
atrial and ventricular systole occur at the same time
Endocardium
The tissue that covers the inside surfaces of the heart and the blood vessels leading to and from the heart is called endothelium. This specialized type of epithelium forms a smooth lining that reduces friction as blood flows through the cardiovascular system. Additionally, it plays a crucial role in regulating various functions, including inflammation and blood clotting.

The endocardium is a thin layer of tissue that lines the inside of the heart chambers and heart valves. It is located beneath the myocardium (muscle layer) and covers the inner surface of the heart.
The main tissue of the heart wall is cardiac muscle tissue, also known as myocardium. This specialized muscle is responsible for the contraction and pumping action of the heart. The heart wall also includes an outer layer called the epicardium and an inner lining called the endocardium, which help protect and support the heart's function.
The pericardium is the sac surrounding the frog's heart.
