high density liprisome
The low-density lipoproteins transport cholesterol from the liver to specific cells and the high-density lipoproteins remove excess cholesterol from the body cells and return it to the liver where it can be excreted in bile.
Cholesterol does not block your windpipe. If your windpipe is blocked, there is another cause. It could be asthma, infection, or a tumor. It could be something else. Excess cholesterol blocks your arteries. That cuts off your blood flow. Sometimes when it cuts off your blood flow, it keeps your heart from getting enough blood so that part of the muscle in your heart does not get blood and oxygen. That is called a heart attack. If not treated real soon, your heart muscle dies. You may die. If it cuts off blood to your brain, it is called a stroke. Again, you may or may not have enough time to get it treated. Of course, if it cuts off blood to the place in your brain that controls heart beat or breathing, you die. Then cholesterol plugs also break off and clog arteries and cause the same problems. Still, they are not the problem in your wind pipe.

Bile is the major vehicle for cholesterol excretion from the body, and bile salt keeps the cholesterol dissolved within bile. to much cholesterol or to little bile salt is what causes gallstones to happen. they are made up of cholesterol. see page 885 anatomy and physiology 8th
arteries and veins. plus the constant pumping of the blood
Your heart keeps pumping blood. The reason people have heart attacks is because your heart never stops pumping blood but if you aren't active enough and you eat too much fat and cholesterol your arteries get clogged and blood can't pass through but your heart doesn't stop pumping blood.
seawater
Cholesterol is a substance in the cell membrane that helps stabilize and strengthen the membrane, preventing it from breaking too easily. It helps maintain the fluidity and integrity of the cell membrane.
Janitor comes to mind
Nothing, it is only pressure that keeps blood moving in the right direction in arteries. Veins have valves that prevent backflow of blood, but arteries do not.
your heart is a pump and keeps the blood flowing
