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 ventricles, on the other hand, have a very thick myocardium to pump blood to the lungs or throughout the entire body. The right side of the heart has less myocardium in its walls than the left side because the left side has to pump blood through the entire body while the right side only has to pump to the lungs. The heart contains 4 chambers: the right atrium, left atrium, right ventricle, and left ventricle.
