    VEIN FROM LEFT LUNG TO LEFT HEART INSIDE LINING OF KEART HEART MUSCLE BAG OF TISSUE SURROUNDING HEART GREAT VEIN FROM BODY AND LEGS HE heart is a powerful hollow muscle divided, by a wall down the middle, into two main divisions —a right and a left. Each division has two chambers which work together as a unit. The blood stream flows from the body into the right side of the heart through veins. From there it is pumped to the lungs where it gets rid of a waste gas (carbon dioxide) collected from the body cells and picks up a load of oxygen to carry to the body cells. After passing through the lungs the blood stream flows into the left side of the heart from which it is pumped to the body through arteries. The drawing on this page is not an exact representation of the heart in cross section, but rather a pictorial diagram to show the course taken by the blood from the body —>» to the heart —» to the lungs —» back to the heart —~» and out to the body again.
