Which is mainly affected during heart attack the organ that pumps blood the vessel that carries oxygenated blood the vessel that carries deoxygenated blood or where gas and nutrient exchange occur?

Answer 1

The most affected organ is the heart (organ) itself. The cause of a heart attack is when the arteries that feed the heart are blocked either by a clot or build-up of plaque. When the heart does not get enough blood, and therefore not enough oxygen, it sends out pain or distress signals- stabbing, crushing, or clenching chest pain, Back pain, jaw or left arm pain, or pressure. The location of the pain is different for each individual and can vary depending on the location of the blocked artery. If the heart is deprived of enough oxygen for a long enough period of time, the heart muscle starts to die. Each cardiac artery feeds a certain area of the heart. So, depending on which artery is blocked, the heart attack can be more or less catastrophic depending on which area of the heart is damaged.
