1 Answer

Answer :

Think of your arteries as tubes in your heart, allowing blood flow. Now, some peoples tubes are very brittle and rigid. Those are unhealthy. People with tubes that stretch, yet return to their size are very healthy. It’s like your lungs ability to stretch out as you take a deep breath, then another without letting the first out.
