Question

which would disrupt homeostasis in the circulatory system and cause a heart attack?
○ a burst blood vessel in the brain, reducing regulation of the heart
○ a blockage in an artery in the heart, reducing blood flow to the heart muscle
○ destruction of the alveoli, causing reduced gas exchange

Explanation:

A blockage in an artery in the heart reduces blood - flow to the heart muscle, disrupting homeostasis in the circulatory system and can lead to a heart attack. A burst blood vessel in the brain affects the nervous system and regulation of the heart indirectly. Destruction of the alveoli affects the respiratory system and gas exchange, not directly the circulatory system's homeostasis related to heart attacks.

Answer:

a blockage in an artery in the heart, reducing blood flow to the heart muscle
