Any object or particle carried by the blood that has the potential to clog or obstruct an artery, vein, or capillary is known as an embolus. Blood clots and fat globules are examples of such materials. A blood clot that forms in a blood artery in one section of the body can be swept along by blood passing through it. It may be able to pass through blood vessels in most cases. However, it is likely to come with a channel that is too tiny for it to travel through at some point, and it will become securely stuck there, cutting off the flow of blood via that blood artery. This is referred to as ‘embolism,’ and it can have serious implications. It might happen without notice and without any preceding warning indications.
An embolism can be produced by air bubbles, lipid globules, or small amounts of amniotic fluid, in addition to blood clots. The condition is known as thromboembolism when a blood clot is the source of obstruction, as in the example above. When an embolism occurs in an artery supplying the lungs, it is one of the most serious types of embolism. Pulmonary embolism is the medical term for this condition, which can be fatal. Fortunately, with quick medical care, it can be successfully resolved.
