what is the main tissue of heart wall
Muscle tissue. The heart wall is made of 3 layers: epicardium, myocardium and endocardium.
Epicardium. The epicardium is the outermost layer of the heart wall and is just another name for the visceral layer of the pericardium. Thus, the epicardium is a thin layer of serous membrane that helps to lubricate and protect the outside of the heart. Below the epicardium is the second, thicker layer of the heart wall: the myocardium.
Myocardium. The myocardium is the muscular middle layer of the heart wall that contains the cardiac muscle tissue. Myocardium makes up the majority of the thickness and mass of the heart wall and is the part of the heart responsible for pumping blood. Below the myocardium is the thin endocardium layer.
Endocardium. Endocardium is the simple squamous endothelium layer that lines the inside of the heart. The endocardium is very smooth and is responsible for keeping blood from sticking to the inside of the heart and forming potentially deadly blood clots.

could you make it a bit easy for me please
Myocardium, a muscle tissue
The main tissue of the heart wall is known as myocardium. It is a specialized type of muscle tissue that forms the majority of the heart wall. The myocardium is responsible for the contraction of the heart, allowing it to pump blood throughout the body.
To find this information, you can refer to reliable sources such as textbooks or reputable websites that cover anatomy and physiology. These sources often provide detailed explanations of the different tissues that make up the heart and their functions.
