Too Many Babies Born to Teens, Says CDC. Nearly one in five babies born to a teenage mom in the U.S. are not the motherâs first baby, according to a report released Tuesday by the Centers for Disease Control and Prevention. In North Carolina, more than one in four babies born to a teen are not her first. The report reveals that although teen birth rates in the U.S. have been declining for the last two decades, of 367,000 babies born in 2010 to mothers who are 15 to 19 years old, 18.3 percent were repeat births.

The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face. There are two carotid arteries, one on the right and one on the left. In the neck, each carotid artery branches into two divisions:
Major blood vessels include  the Inferior Vena Cava, Superior Vena Cava, Pulmonary Artery,  Pulmonary Veins, Coronary Artery, and Aorta.    The four parts of the circulatory system are the heart, artery,  capillaries, and the veins. The heart is the center or the main  source of the circulatory system, it pumps blood throughout a  network of blood vessels. An artery is a blood vessel that carries  blood away from the body. Capillaries are very thin vessels that  gases, nutrients, and wastes pass to body cells.
