Hemoglobin exchanges oxygen for carbon dioxide molecules then transport them back to the lungs. Along the way, fat, sugars and plaques are also picked up. These parts are sticky a great deal like sludge and adhere to the vessel walls. This narrows the passage causing the walls to turn out to be ridged and tough increasing the force essential to transfer the blood through the narrow openings.
