Hardening of the Arteries or Atherosclerosis

James Anderson

Heart attacks and strokes are mainly caused by a blockage that forestalls blood from flowing to the guts or the brain. The most common reason for this is often a build-up of fatty deposits on the inner walls of the blood vessels that provide the center or the brain. This makes the blood vessels narrower and fewer flexible. It is sometimes called hardening of the arteries or atherosclerosis. The blood vessels are then more likely to urge blocked by blood clots. When that happens, the blood vessels cannot supply blood to the guts and brain, which become damaged. Tobacco smoke is filled with substances that damage your lungs, blood vessels and heart. They take the place of the oxygen within the blood that your heart and brain got to work properly.
