Document Summary
Keep your heart healthy with the right foods. Coronary artery: artery/blood vessel that is feeding the heart. Ldl low-density lipoprotein infiltrates endothelium, filled with inflammation -> calcify. Artery blockages can start developing in 20s & 30s. Coronary artery disease is characterized by blockages in arteries that feed heart. Hdl: cholesterol scavenger that brings cholesterol back to liver for possible removal from body. Ldl may get oxidized, no longer following course it should, not stopping at bus stops. Litters roadway w/ cholesterol - this infiltrates artery walls, developing into. Platelets gather & clump up -> heart attack or stroke. Over time, this cholesterol build up blocks traffic, clogging the flow -> blocked coronary arteries & heart attack or at brain -> stroke. Atherosclerosis: buildup of cholesterol or coronary artery disease (if it happens in heart) The number of ldl buses increase due to: Cigarette smoking - oxidation, bus driver more likely to crash into artery walls.
