Aziz goes to the doctor and has a blood cholesterol test done. The results show that his total cholesterol is slightly high, his HDLs are very high, and his LDLs are low.

A. Neither LDL nor HDL are involved in cholesterol regulation. B. It is preferable to have a high concentration of high-density lipoproteins (HDLs) in the plasma because HDLs operate to remove cholesterol from the peripheral tissues and carry it to the liver, which secretes it into the small intestine.
