Question

How do the lipoproteins ldl and hdl influence heart disease risk?

a. ​hdl are affected by the amount of cholesterol we eat in our diet.
b. ​hdl play an important role in scavenging cholesterol from the tissues for disposal.
c. ​ldl are much lighter in weight since they do not contain as much cholesterol to take to the cells.
d. ​ldl benefit the heart by transporting cholesterol to the tissues and away from blood.
e. ​hdl transport dietary fat to the liver and help keep fat from being stored in the liver?

Answer 1

Answer: b. HDL play an important role in scavenging cholesterol from the tissues for disposal

HDL or high density lipoprotein is better known as the good cholesterol. It is a type of cholesterol that works exactly opposite LDL. When a person has a high HDL he is most likely less at risk of a heart disease as it protects the blood vessels to become narrow.

Answer 2

The answer is :b. hdl play an important role in scavenging cholesterol from the tissues for disposal.

HDL means high density lipoprotein and it's known as the 'good cholesterol'. When it's high it's a sign that it's removing the cholestrol present in the tissues and bring it to the liver.
On the other hand, LDL (low density lipoprotein) is the 'bad cholestrol' and will cause heart disesase because it leads to the acumulation to the cholestrol in the tissues.
