when a person suffers a stroke, it is initially caused by damage to the___ a) circulatory system b) nervous system c)pulmonary s
Makovka662 [10]

Answer:

The correct answer would be a) circulatory system.

A stroke is primarily caused due to reduced or interrupted supply of blood to the brain.

The blood supply is usually reduced as a result of blockage or bursting of an artery carrying blood to the brain.

Consequently, the brain cells experience a lack of oxygen and nutrients due to which they begin to die.

Thus, stroke is initially caused by damage to the circulatory system.
