The heart is basically a pump. The heart is made up of specialized muscle tissue, called the myocardium. The heart's primary function is to pump blood throughout the body, so that the body's tissues can receive oxygen and nutrients and have waste substances taken away.Like any pump, the heart requires fuel in order to work. The myocardium requires oxygen and nutrients, just like any other tissue in the body.However, the blood that passes through the heart's chambers is only passing through on its trip through the body-this blood does not give oxygen and nutrients to the myocardium.he heart is basically a pump.
