Why does Atherosclerosis occur in arteries and not in veins?
Atherosclerosis occurs when LDL (Low Density Lipoproteins) get oxidized. Since the plasma in the arteries contains plenty of oxygen to oxidize the LDL's it occurs mostly in arteries. In the veins, there is little oxygen to be found, so it is much more likely to happen in the arteries for that reason.
Lipoproteins are important for?
Lipoproteins are used to transport lipids in the body. They are also integral parts of cell membranes and transporter molecules.
What scale is used to determine an earthquakes density?
The Richter Scale is used to determine the earthquake density. The scale is measured from low as 1 to high as 10.
What type of cholesterol that may put patients at risk of heart disease?
Low-density lipoprotein
Salinity in the ocean is highest in regions where is high and is low?
Salinity in the ocean is highest in regions where evaporation is high and precipitation is low. Density in seawater is determined by both temperature and salinity.
What are Intermediate-density lipoproteins?
IDLs are short-lived lipoproteins containing about 30% cholesterol that are converted in the liver to low-density lipoproteins (LDLs)
The substances that serve as the major vehicles for fat transport in the bloodstream are?
The substances that serve as the major vehicles for fat transport in the bloodstream are lipoproteins, specifically chylomicrons, very low-density lipoproteins (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). These lipoproteins carry fats, such as triglycerides and cholesterol, to various tissues in the body for energy production or storage.
What are two types of lipoproteins?
high density lipoprotein and low density lipoprotein.
Where are very low-density lipoproteins made?
Very low-density lipoproteins (VLDL) are made in the liver. They are produced by the liver to transport triglycerides throughout the body.
Does Cardiovascular endurance exercise increase levels of low-density lipoproteins?
No
How is the production of endogenous very low-density lipoproteins decreased?
Exercise
A high risk of heart attack correlates with high blood levels of what?
A high risk of heart attack correlates with high blood levels of low-density lipoproteins. Lipoproteins are responsible for transporting triacylglycerol's and cholesterol in the blood among all the tissues in the body.
What describes lipoproteins?
Lipoproteins are complexes of lipids and proteins that transport cholesterol and other fats in the blood. They are categorized based on their density, with high-density lipoproteins (HDL) being considered beneficial for heart health, while low-density lipoproteins (LDL) are associated with increased risk of heart disease. Lipoproteins play a crucial role in maintaining lipid balance in the body.
How are fats transported in the blood?
Fats are transported in the blood as lipoproteins, which are complex particles that consist of fats (such as cholesterol and triglycerides) surrounded by proteins. The main types of lipoproteins involved in fat transport are chylomicrons, very low-density lipoproteins (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). These lipoproteins help transport fats to various tissues in the body for energy production and storage.
Endogenously produced cholesterol is packaged in for delivery to cells of the body?
low-density-lipoproteins
What are synthesized by the liver to transport fat to the rest of the body?
very low density lipoproteins
What organ contains special receptors for removing low-density lipoproteins from the circulation?
Liver
