What does the term occlusion refer to?

The term occlusion specifically refers to a blockage or obstruction, particularly in the context of blood vessels. When discussing occlusion, it often relates to conditions where blood flow is hindered due to factors such as fatty deposits, also known as atherosclerosis, or thrombus formation within the blood vessels. This blockage can impede normal circulation, potentially leading to serious health issues. Understanding occlusion is crucial in medical fields, especially when dealing with cardiovascular health, as it directly affects blood flow and oxygen delivery throughout the body.
