In this episode we talk about what happens to our circulation system and blood vessels as we age. We also discuss how mitochondria and Nitric Oxide play a role in our blood circulation. Finally, we will talk about how exercise or antioxidants can impact the health of our blood vessels. Our guest today is Dr. Song-Young Park. He completed his post-doctoral research fellowship in department of cardiology at Boston University School of Medicine, and earned his PhD in integrative physiology from the University of Utah in 2015. Utilizing an integrative approach, Dr. Song-young Park's research examines the impact of age and disease on circulation systems and blood pressure regulation. Heart disease is the #1 cause of death in North America and worldwide. Heart disease can be caused by high blood pressure due to stiffness in the arteries. Arterial stiffness can be caused by physical stress, mental stress or aging. Mitochondria live in every cell of our bodies, they are the power plants of about every living animal and plant. They take the nutrients in our body such as the sugars, fats and proteins and turn them into energy. They also need oxygen to create this energy. We will be talking about mitochondria a lot more in future episodes, but lets move on for now. The vascular or circulation system contains the vessels that carry blood and lymph through the body. The arteries carry blood which is full of oxygen to all the cells of body. The veins take away tissue waste from the body.    Endothelium is the most inner layer of the blood vessel. The mitochondria in the Endothelium produce the energy that helps to release Nitric Oxide, and this Nitric Oxide is then absorbed by the smooth muscles of the blood vessels to expand/dilate them when there is more blood flowing.
