THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Atherosclerosis, sometimes called “hardening of the arteries, ‘’ occurs when fat, cholesterol, and other substances build up in the walls of arteries. These deposits are called plaques.

Detailed explanation-2: -Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis.

Detailed explanation-3: -Each artery is a muscular tube lined by smooth tissue and has three layers: The intima, the inner layer lined by a smooth tissue called endothelium. The media, a layer of muscle that lets arteries handle the high pressures from the heart. The adventitia, connective tissue anchoring arteries to nearby tissues.

Detailed explanation-4: -High blood pressure, high cholesterol, diabetes, obesity, smoking, stress and anxiety, a sedentary lifestyle and a family history of heart disease are all key risk factors for arterial plaque buildup.
