If you need a boy dog name for your Shepherd, check the male German Shepherd names list. Otherwise, take a look at the list of names and meanings below. One more thing . . . my neighbor raises German Shepherds and my favorite of her female German Shepherd names (so far) is Deja. That just seems like a cool dog name.
The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.
The right side of the heart sends blood to the lungs to pick up oxygen before going to the left side of the heart. There it is returned to the body full of oxygen. Blood now goes back to the heart from the lungs by way of the pulmonary veins and flows into the left atrium (LA).
