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 heart muscle, like every other organ or tissue in your body, needs oxygen-rich blood to survive. Blood is supplied to the heart by its own vascular system, called coronary circulation. The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle. The right coronary artery supplies blood mainly to the right side of the heart. The right side of the heart is smaller because it pumps blood only to the lungs. The left coronary artery, which branches into the left anterior descending artery and the circumflex artery, supplies blood to the left side of the heart.
