Question

The sudden death of brain cells when their blood supply is interrupted is called

A. a heart attack.
B. a stroke.
C. hypertension.
D. atherosclerosis.

Answer 1

The only correct answer in this case is B - a stroke.

None of the other answers could be counted as correct here.

While A - a heart attack is conceptualy similar, when we're talking about a heart attack, we're talking about not enough oxygen that gets delivered to the heart - because something is blocking it.

C - hypertension on the other hand means someone has a higher blood pressure than is usual for a regular human being, which puts more strain on his cardiovascualr system.

and D - atherosclerosis doesn't come even close to be correct :)

Answer 2

Option B, a stroke

Step-by-step explanation:

A stroke is caused by an interrupted blood supply which leads to the death of brain cells. The strokes are of two types –

a) Ischemic attack– In this a blood clot causes blocking of blood vessel. Ischemic attack is of two types –

1. Thrombotic – This occurs primarily due to blood clotting in any vessel or artery

2. Embolic. This occur when a part of thrombus travels from its original site and blocks some other artery

b) Hemorrhagic stroke – In this a blood vessel burst inside a brain thereby causing brain hemorrhage.
