Narrowed Artery (atheroma)
Light micrograph illustrates a transverse section of an artery exhibiting partial obstruction due to the presence of an atheroma (depicted in light pink at the bottom). Atheroma refers to the accumulation of lipid-rich materials within the arterial wall, which can significantly diminish the lumen's diameter (the inner space shown in white). This narrowing impedes adequate blood flow, resulting in ischemia to the tissues that depend on that arterial supply. In cases where the arteries supplying the heart become completely occluded, this condition may lead to a myocardial infarction, commonly known as a heart attack.
