Very strong muscle: and a wonderfully efficient pump. It gets Oxygen and nutrition through the coronary arteries and if you think about it in an average, will beat 32 million times in a year!!! (that is over 2.5 billion times in someone 80 years old!!!) It works great but you have to take care of it!!!
