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.
[edit]. The heart has two sides: the left side and the right side. Each side of the heart is divided into two parts, called the atrium and the ventricle. The atrium is the top part. The ventricle is on the bottom. Both sides of the heart have a blood vessel (a vein) through which blood flows into the atrium. Valves are like doors that control where blood goes. Valves separate the atrium from the ventricle. Another set of valves controls the flow of blood from the ventricle to the artery that sends blood back into the body.
