HDL (high-density lipoprotein) is the substance that carries excess cholesterol from the bloodstream to the liver to be broken down and removed from the body.
excess cholesterol may be deposited in the walls of the arteries.
HDL(High-Density Lipoprotein) is the smallest of the lipoprotein particles. They are the densest because they contain the highest proportion of protein.HDL cholesterol, or "good" cholesterol, appears to scour the walls of blood vessels, cleaning out excess cholesterol. It then carries that excess cholesterol -- which otherwise might have been used to make the "plaques" that cause coronary artery disease -- back to the liver for processing. HDL cholesterol level helps fight heart disease.
There are two main types of cholesterol transporters in the body: LDL (low-density lipoprotein) and HDL (high-density lipoprotein). LDL carries cholesterol from the liver to cells for use, but can also deposit excess cholesterol in the arteries, leading to plaque formation. HDL helps remove excess cholesterol from the arteries and transports it back to the liver for excretion from the body.
Cholesterol is primarily transported in the body within lipoproteins, such as LDL (low-density lipoprotein) and HDL (high-density lipoprotein). LDL carries cholesterol from the liver to the cells, while HDL removes excess cholesterol from the cells and transports it back to the liver for excretion or recycling.
Cholesterol is in everyone's body, and it needs to be; cholesterol is the basis of all other hormones. However, modern diets and relative inactivity can lead to a buildup of excess cholesterol which is harmful. Consumption of saturated fats is a major source of excess cholesterol.

Cholesterol
These transport vehicles are called high-density lipoproteins (HDL). HDL picks up excess cholesterol from cells and transports it to the liver where it can be broken down and eliminated from the body. HDL is often referred to as "good cholesterol" because of its role in removing cholesterol from the bloodstream.
An excess of cholesterol in the cell membrane can lead to decreased fluidity and flexibility of the membrane, potentially affecting the cell's ability to function properly.
The liberal excretes excess cholesterol in bile
Anything above 200mg/dl is excess. thanks
