LDL's are cleared by the liver. HDL is generally fatty acid poor and cholesterol ester rich. It contains a different apolipoprotein which helps the body tell it apart from LDL. Simply put, it transports cholesterol back to the liver from other areas of the body.
In practice, HDL cholesterol is often called the 'good' cholesterol and LDL cholesterol is called the 'bad' cholesterol. The reason for this is that HDLs help transport cholesterol in the body to the liver where the body then prepares to excrete it. LDLs, on the other hand, actually transport cholesterol from the liver to cells in the body.
