Question

Which step occurs first in the process of atherosclerosis?

Low-density lipoprotein becomes oxidized, causing inflammation and damage to arterial walls.
Pressure from blood flow causes plaque to rupture, and a blood clot forms.
Oxygen and nutrients are deprived from the tissues below the damaged blood vessel.
Low-density lipoprotein accumulates in the arterial wall and expands, reducing blood flow.

Answer 1

The first step in the process of atherosclerosis is the accumulation of low-density lipoprotein in the arterial wall, reducing blood flow.

Step-by-step explanation:

In the process of atherosclerosis, low-density lipoprotein (LDL) accumulates in the arterial wall and expands, reducing blood flow. This step occurs first as LDL particles infiltrate the inner lining of the artery and become oxidized, causing inflammation and damage to arterial walls. As a result, pressure from blood flow can lead to the rupture of plaque, which forms a blood clot, and eventually oxygen and nutrients are deprived from the tissues below the damaged blood vessel.
