narrowed vessels result in oxygen starvation. Narrowing also causes acidosis (an increase in tissue acidity) and increases blood viscosity (thickness). Ultimately, blood stops flowing through the capillaries

Arteriosclerosis slowly reduces blood flow through the arteries to the brain?
Yes. And to other parts of the body as well. As plaque builds up, the arteries narrow, blood pressure builds. The chance of heart attack and stroke increases the more the arteries narrow.

What happens to your arteries when drinking alcohol?
is drinking a moderate amount of Jack Daniels bad if you have clogged carotid arteries
What does an artery have that a vein does not?
Arteries carry oxygenated blood; veins carry de-oxygenated blood. Arteries have much thicker muscular wall (of muscle and elastic fibres). Arteries have narrow passageway for blood; veins have a wider passageway. Arteries have higher blood pressures. Extra info. if you need it Veins have flaps of valves while arteries do not.
What body parts are involved in a heart attack?
The heart, of couse, but the cause is due to blocked or narrow arteries with blood clots.
What happens if you swallow nitroglycerin tablet?

What is atherosclerotic calcifications of the intracranial internal carotid arteries?
When looking at a phrase like this, it is easiest to break it down into individual words, until you become fluent in reading medical terminology. Atherosclerotic refers to the build up of atheroma, (cholesterol or fat) in the arteries, that leads to the passageway through the artery becoming narrow. Calcification is the build up of calcium, causing the artery to harden. Intracranial means within the cranium (Skull). Internal Carotid Arteries are major arteries that supply the brain. So this phrase means, there are fat and calcium salt deposits within some major arteries to the brain, that have caused the arteries to become more narrow and harden.
What type of blood vessel can begin to narrow and restrict blood flow due to old age or an unhealthy lifestyle?
The coronary artery
