Effects of High LDL Cholesterol Similar to a heart attack, most strokes occur when there is a lack of oxygen, but in this case, to the brain. Once again, the plaque that builds up from excess LDL-C breaks open and a clot forms—blocking an artery that supplies blood to the brain. Without oxygen, brain cells start to die and symptoms begin to appear.

Understanding Your Cholesterol Test Results Cholesterol is a waxy, fat-like substance. Your liver makes all the cholesterol your body needs. But you take in more cholesterol from certain foods, such as those from animals. If you have too much cholesterol in your body, it can build up in the walls of your arteries (as plaque) and eventually harden. High-density lipoproteins (HDL). 2  This is the good cholesterol.. 3  It transports bad cholesterol from the blood to the liver, where it is excreted by the body. 4  Your HDL is another part of the equation that identifies the risk of a cardiovascular event.

Where is Cholesterol Produced in the Body? HDL cholesterol is considered the good cholesterol because its primary role is to transport LDL's back to the liver where it is disposed of. HDL is comprised of mainly protein and makes up about 20% of the cholesterol in the body. It helps prevent atherosclerosis by preventing LDL cholesterol from depositing and forming plaques in the arteries.

10 Nutrition Myths Dietary cholesterol—the fat-like molecules in animal-based foods like eggs—doesn’t greatly affect the amount of cholesterol circulating in your bloodstream. Your body makes its own cholesterol, so it doesn’t need much of the kind you eat. Instead, what fuels your body’s cholesterol-making machine is certain saturated and trans fats.

The Reproductive System These endocrine glands produces a variety of hormones and some of these play a critical role in helping your body adapt to physical and emotional stress. pancreas This endocrine gland produces a hormone called insulin which helps your body to control blood sugar levels in the bloodstream. ovaries These endocrine glands produce the hormones estrogen and progesterone which help regulate the female reproductive cycle and are responsible for producing and maintaining female sex characteristics.

If the brain is 60% fat, is it affected when body fat becomes very low due to starvation or dieting? The brain does not contain fat cells, such as the kind that shrink when energy is scarce during dieting. All cells in the body, including the brain, are partially composed of lipids, since lipid molecules are the main building block of the extracellular (outer cell) membrane.

Brain The brains of vertebrates are made of very soft tissue. Living brain tissue is pinkish on the outside and mostly white on the inside, with subtle variations in color. Vertebrate brains are surrounded by a system of connective tissue membranes called meninges that separate the skull from the brain.

Overview Carotid artery disease is caused by a buildup of plaques in arteries that deliver blood to your brain. Plaques are clumps of cholesterol, calcium, fibrous tissue and other cellular debris that gather at microscopic injury sites within the artery. This process is called atherosclerosis.

What are blood lipids? Cholesterol is the main lipid. It is made up of different parts such as: 1  LDL cholesterol, or “bad” cholesterol, is the main lipid that causes damaging buildup and blockage in your arteries.  HDL cholesterol is actually a “good” type of cholesterol that helps to prevent cholesterol from building up in your arteries.

Hypercholesterolemia  (High Blood Cholesterol) Your body makes all the cholesterol it needs. However, cholesterol also is found in some of the foods you eat. Cholesterol travels through your bloodstream in small packages called lipoproteins (lip-o-PRO-teens). These packages are made of fat (lipid) on the inside and proteins on the outside.

Learning, Your Memory, and Cholesterol One of the many important roles cholesterol plays in the body is in our nervous system, enabling learning and memory to take place. In fact, one of the reasons that sleep is beneficial to our learning and memory is because it enables our brain to make more cholesterol!n the absence of this-- as yet unknown-- glial factor, neurons formed few synapses, and the synapses they formed were inefficient and poorly functioning. In the presence of glial cells, which secrete the unknown factor, neurons formed many, highly efficient synapses.

- Myelin is composed of about 40% water and the dry mass is composed of about 80% lipids and 20% protein. The mainly lipid composition of the myelin gives it a white hue, hence the reference to the brain’s “white matter.” The main lipid found in myelin is a glycolipid called galactocerebroside.

- 1 LDL cholesterol makes up the majority of the body’s cholesterol. 2  LDL is known as “bad” cholesterol because having high levels can lead to plaque buildup in your arteries and result in heart disease and stroke. 3  HDL cholesterol absorbs cholesterol and carries it back to the liver, which flushes it from the body.

Lipids (fats), Proteins, Digestion & absorption Cholesterol. Fatty substance made in the liver and found in the bloodstream. It is an important part of all cells and is necessary for creating hormones. However it may accumulate in the lining of arteries, such as in the heart, causing heart disease, or in the gallbladder to form gallstones.

Examples Blood cholesterol test. Cholesterol is a fatty substance mostly created by the liver from the fatty foods in your diet and is vital for the normal functioning of the body. Having a high level of cholesterol can contribute to an increased risk of serious problems such as heart attacks and strokes.

Menopause Glossary Introduction. Hypercholesterolemia, or high cholesterol, occurs when there is too much cholesterol in the body. Cholesterol is a soft, waxy, fat-like substance that is a natural component of all the cells in the body. Your body makes all the cholesterol it needs. Added cholesterol, which comes from the foods you eat, may cause harm. High cholesterol raises your risk for heart disease, heart attack, and stroke. When there is too much cholesterol circulating in the blood, it can create sticky deposits (called plaque) along the artery walls. Plaque can eventually narrow or block the flow of blood to the brain, heart, and other organs.
