High blood glucose, also called blood sugar, can harm your baby during the first weeks of pregnancy, even before you know you are pregnant. If you have diabetes and are already pregnant, see your doctor as soon as possible to make a plan to manage your diabetes.
These are the only veins in the body that carry fresh, oxygenated blood. Blood leaves the heart from the left ventricle through the artery called the aorta. The aorta has several branches into other arteries that are carrying blood away from the heart and to the body tissues.
The blood vessels that carry blood away from the heart are called arteries. The ones that carry blood back to the heart are called veins. The movement of the blood through the heart and around the body is called circulation (say: sur-kyoo-LAY-shun), and your heart is really good at it â it takes less than 60 seconds to pump blood to every cell in your body.
