Q:Cholesterol in the body is produced by the liver.
The correct answer is: • True
Explanation:
The liver produces cholesterol in the body. Dietary sources (animal-derived foods) also contain cholesterol. Cholesterol plays a number of roles in maintaining vital body functions including hormone production and digestion.
Elevated blood cholesterol has been linked to serious health complications, but high cholesterol typically does not produce symptoms or signs. Therefore, many people are unaware that their cholesterol level is high. Your doctor can advise you on how often your cholesterol levels should be tested.
Anyone of any age can have high cholesterol levels. The process of cholesterol buildup in arteries has been shown to begin during childhood. With rising rates of childhood obesity, more and more children are at risk for developing high cholesterol levels and cardiovascular disease.
Q:"Plaques" are cholesterol deposits in the blood vessels and arteries.
Q:"Plaques" are cholesterol deposits in the blood vessels and arteries.
The correct answer is: • True
Explanation:
The term "plaque" refers to the deposition of cholesterol and other substances on the walls of blood vessels, eventually compromising circulation. Cardiovascular disease occurs when plaque obstructs the coronary arteries that supply blood to the heart. Complete blockage of a coronary artery leads to an interruption of blood flow to the heart, or a heart attack. Blood clots also form on areas of plaque and can obstruct the arteries.
Both heart attack and stroke involve the interruption of blood flow to an organ due to a blockage within an artery. A heart attack results from a blocked coronary artery, while a stroke results from blockage of an artery in the brain.
