Cholesterol is a fatty substance that is an important part of the outer lining (membrane) of cells in the body of animals. Cholesterol is also found in the blood movement of humans. The cholesterol in a person's blood originates from two sources; dietary intake and liver production. Dietary cholesterol comes mainly from meat, fish, and dairy products. Organ meats, such as liver, are especially high in cholesterol content, while foods of plant origin contain no cholesterol. After a meal, cholesterol is absorbed by the intestines into blood circulation .This cholesterol-protein coat complex is called a chylomicron.
The liver is capable of remove cholesterol from the blood circulation as well as manufacturing cholesterol and secreting cholesterol into the blood circulation. After a meal, the liver removes chylomicrons from the blood. In between meals, the liver manufactures and secretes cholesterol back into the blood circulation.
