Which of the following is the correct description of a myocardial infarction and what it is caused by? View Available Hint(s) Which of the following is the correct description of a myocardial infarction and what it is caused by? A region of heart muscle dies due to a lack of glucose supply. A region of heart muscle becomes overly active. A region of heart muscle dies due to a lack of blood supply. A region of muscle becomes inactive due to a lack of neuronal stimulation.

The answer that is correct is the: Third statement.

Explanation:

Heart is one of the most essential organ in the human body as it is responsible for supplying nutrients and oxygen to all the parts of the body and  collecting waste materials and carbon dioxide from all the parts of the body through the blood.The cells (fibroblasts, cardiomyocytes, etc.) of the heart itself are provided with the nutrients and oxygen by a specialized blood vessel called the Coronary Artery.Waste materials and carbon dioxide are removed from the cells of the heart by another specialized blood vessel called the Coronary Vein.Due to aging or consumption of excess fat and cholesterol rich food, the concentration of lipid molecules in blood get increased beyond normal. These lipid molecules get deposited in the walls of the arteries, including the coronary artery, forming plaques, resulting in the development of atherosclerosis.This reduces the diameter of the arteries, including the coronary artery, thereby reducing the blood flow through them.Due to plaque deposition, the coronary artery is incapable for carrying sufficient oxygen and nutrients to the heart cells, causing their death.This results in the development of a sharp pain in the chest that is diagnosed as Heart Attack or Myocardial Infarction.

Cell division is important to single celled organisms because it allows the cells to reproduce. through cell division, cells make exact copies of themselves. when single celled organisms go through cell division, they make exact copies of themselves which is how they reproduce.
