LDLs ( low density lipoproteins) that's why the cholesterol in combination with LDLs is called " bad cholesterol".

The myocardium or heart muscle is nourished with oxygen-rich blood. The vessel that delivers the blood to the myocardium is called Coronary Arteries.
The coronary artery delivers oxygenated blood to the heart. The coronary arteries supply the heart muscle with oxygen and nutrients.
The renal arteries of the cardiovascular system delivers waste to the kidneys.
The coronary arteries deliver blood to the muscles of the heart.
The blood going out from the arteries is full of oxygen. It delivers that oxygen to the organs, therefore when it returns in the veins, it contains carbon dioxide
Usually arteries carry blood rich in oxygen to body cells. However, arteries do not always carry oxygen. The word artery is an anatomical term meaning vessels leaving from the heart.
Blood vessels, including arteries, arterioles, and capillaries, deliver blood to your body tissues. These vessels carry oxygen and nutrients to cells throughout the body, allowing for essential functions and processes to occur.
The carotid artery supplies oxygenated blood to the head and neck. The radial artery delivers blood to the hands. It is important for the carotid and radial arteries to be synchronized because they work together to help the body function.
LDL (low-density-lipoproteins)- transport cholesterol to body cells where they are used in various ways. It is also called the bad cholesterol. HDL (high-density-lipoproteins)- transport cholesterol from the tissue cells (or arteries) to the liver for disposal in bile.For this purpose it is called the good cholesterol.
The renal artery supplies blood to the kidneys. All arteries are muscular since they contain a layer tunica muscularis.
All I honestly know about this is the higher the numbers the worse your cholesterol and that there are foods you can eat to lower it. I also know that WebMD can answer a lot of these questions.
