What is the heart made from?
The heart is made up of 3 main layers. The outermost layer is the epicardium, a thin membrane that helps to lubricate the heart.
Next is the myocardium: this is the thicker layer of the heart and contains cardiac muscles. These muscles pump throughout your life to send blood all the way around the body. Your heart beats about 100,000 times in one day- in an average human lifetime, it will beat more than 2.5 billion times!
The final layer is the endocardium. This smooth layer lines the inside of the heart and prevents blood from sticking and forming clots.
