Final answer:
Pulmonary Infarction is the death of lung tissue due to a blocked pulmonary artery, similar to myocardial infarction in the heart but occurring in the lungs.
Step-by-step explanation:
A Pulmonary Infarction refers to the death of a portion of lung tissue due to a blockage in the pulmonary artery which cuts off the blood supply. While it shares some similarity in process with a myocardial infarction, it affects the lungs rather than the heart. In a myocardial infarction, which is commonly known as a heart attack, there is a complete blockage of the coronary arteries, leading to the death of cardiac muscle tissue due to the lack of blood flow and oxygen.
This kind of infarction in the heart is often caused by blood clots or plaque rupture. Similarly, a pulmonary infarction occurs when an embolus, such as a blood clot, blocks a pulmonary artery, restricting blood and oxygen flow to the lung tissue and resulting in tissue death.
