  Today I’m going to talk about “what made up our heart “! We all learn about the heart’s structure in the  Junior Biology class,and also recite it so hard.But what's their English name ? Let's check it out together!

  At first,human’s heart was classified as the circulatory system. It is a muscular organ,which pumps blood through the whole body’s blood vessels.And it is in the middle of the thorax.
