Coronary artery disease, also called coronary heart disease, or simply, heart disease, affects millions of Americans. This serious condition is a result of plaque buildup in your arteries. What Is Coronary Artery Disease? The arteries, which start out smooth and elastic, get plaque on their inner walls, which can make them more rigid and narrowed. This restricts blood flow to your heart muscle, which can then become starved of oxygen.
The least sensitive skin on the human body is found in the heelarea. This is because there are very little nerves in the heel to feelthings. If there were too many nerves in oâ¦ur heels then walkingwould be far too painful. The second least sensitive is the elbow.
Within the body, the tissues with the greatest resistance are bone and fat - nerves and muscle have the least resistance. That said, the majority of the body's resistance is in the skin - the dead, dry cells of the epidermis (the skin's outer layer) are very poor conductors. Depending on the person, the resistance of dry skin is usually between 1,000-100,000 Ohms. The skin's resistance is much lower if it is wet or burnt/blistered.
