PART VIII.
FORMULA FOR THE LESSON ON THE HEART AND THE CIRCULATION OF THE BLOOD.
1. My heart is shaped like a cone, and placed in my chest near my
breastbone, with its apex pointing downward to my left side. It beats about
seventy times a minute, sending out about two ounces of blood at every
beat.
2. The blood when pure is of a bright red color; it is a liquid made from

3. It passes from my heart to all parts of my body, through pipes called
arteries; these arteries spread out through the body like branches from a
tree.
