Question

Quizplus · Accepted Answer

LDL (Low-Density Lipoprotein) is often referred to as "bad" cholesterol because it transports cholesterol and triglycerides from the liver to the tissues, including the arteries. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain, forming plaque, a thick, hard deposit that can narrow the arteries and make them less flexible. This condition is known as atherosclerosis and can lead to heart disease, heart attack, and stroke.
