A heart attack is classified as what type of malfunction?

A heart attack is classified as a circulatory malfunction because it primarily affects the heart and the blood vessels that are integral to the circulatory system. During a heart attack, commonly known as a myocardial infarction, blood flow to a part of the heart is blocked, often due to a buildup of plaque in the coronary arteries. This blockage deprives heart muscle cells of oxygen and can lead to cell death. Understanding this context is crucial because the circulatory system is responsible for transporting oxygen, nutrients, and waste products throughout the body, and any malfunction within this system, such as that caused by a heart attack, has significant implications for overall health and function.
