Atherosclerosis & Cholesterol Flashcards
Topic 1 - Lifestyle, Health & Risk 1.2 Circulatory Health
Once the plaque is built, what effects would the narrow lumen have?
Blood flow restricted and increases blood pressure
What affects the level of cholesterol?
High cholesterol levels can result from lifestyle choices, such as having a diet high in saturated fats, and smoking.
What is atheromas?
The deposition of materials in the walls of arteries causing a blockage.
What are the functions of high-density lipoproteins (HDLs)?
HDLs reduce cholesterol levels in the blood because they transport cholesterol from cells to the liver to be broken down.
It is known as the “good” cholesterol.
What is atherosclerosis?
The blockage of an artery by the buildup of fatty plaques.
How are fibrous plaques in blood vessels formed?
The endothelium of arteries can become damaged by the deposition of white blood cells and lipids.
If white blood cells and fatty materials continue to be deposited in the artery walls, the materials will begin to form hard, fibrous plaque.
What is a lipoprotein?
A cholesterol and a protein combined together and helps to transport cholesterol around the body.
How does cholesterol affect blood clots?
High levels of cholesterol increase the risk of cardiovascular disease because it contributes to atherosclerosis and increases blood pressure blood vessels.
What are the functions of low-density lipoproteins (LDLs)?
LDLs increase cholesterol levels in the blood because they transport cholesterol from the liver to cells in the body.
It is known as the “bad” cholesterol.
What are the 2 types of lipoproteins?
High-density lipoproteins (HDLs) and low-density lipoproteins (LDLs).
