Journey into your body to get an inside view of your cardiovascular system—your heart and blood vessels. You’ll see healthy arteries pulsating rhythmically as blood surges through them. Top experts, including Dr. Mehmet Oz and Dr. John E. Castaldo, talk about what hypertension (high blood pressure) is and how the force of blood from an overworked heart literally tears the lining of your arteries. Witness a beating heart and learn how high blood pressure can lead to atherosclerosis, enlarged heart, heart attack, and stroke. Go inside an eyeball and watch capillaries bursting in the retina due to hypertension. But high blood pressure can be managed. Find out how exercise and the right diet, possibly combined with medication, can prevent hypertension from being the “silent killer.”
