Which organ circulates blood throughout the body and can suffer a heart attack when blocked?

Explanation:
The heart is the organ that pumps blood throughout the body. When a coronary artery feeding the heart muscle becomes blocked, that part of the heart can be starved of oxygen and suffer a heart attack (myocardial infarction). The other organs listed—liver, lungs, and kidneys—play important roles in blood processing and gas exchange, but they do not serve as the body’s main pump, nor do they cause a heart attack when their own blood supply is blocked.
