What is the function of HDL cholesterol in the body?

High-density lipoprotein (HDL) cholesterol plays a crucial role in the body's lipid metabolism. One of its primary functions is to transport cholesterol from the peripheral tissues back to the liver. This process is often referred to as "reverse cholesterol transport." By carrying excess cholesterol away from the arteries and depositing it in the liver, HDL helps to reduce the risk of atherosclerosis and other cardiovascular diseases, as high levels of cholesterol in the bloodstream can lead to plaque buildup in the arteries.

In addition, HDL cholesterol is known for its protective effects against heart disease, as it helps to maintain a healthy balance of cholesterol levels in the body. Therefore, the function of HDL as a carrier of cholesterol to the liver is vital for overall health and well-being.
