Structure of the Heart
There are several different chambers in the heart. The lower chambers are called left and right ventricle. The upper chambers are the left and right atrium. The non-oxygenated blood goes through the right atrium and right ventricle. While the oxygenated blood goes through the left atrium and left ventricle. The aorta is the main artery of the body and is the largest.
What it Happens
One of the many ways that people can have a heart attack, is by the build up of plague. Coronary heart disease is when plague builds up in your arteries. This cuts off the oxygen from getting to the heart muscles. If the blockage isn’t removed or treated quickly enough, it can cause permanent damage or cause death. Eventually, damaged heart tissue is replaced with scarred tissue. This can cause further health problems down the road.
