Detailed explanation-1: -A pulmonary embolism (PE) occurs when a blood clot gets stuck in an artery in the lung, blocking blood flow to part of the lung. Blood clots most often start in the legs and travel up through the right side of the heart and into the lungs. This is called deep vein thrombosis (DVT).

Detailed explanation-2: -A pulmonary embolism is a sudden blockage in your pulmonary arteries, the blood vessels that send blood to your lungs. It usually happens when a blood clot in the deep veins in your leg breaks off and travels to your lungs. A blood clot that travels to another part of your body is called an embolus.

Detailed explanation-3: -A thrombus is a blood clot that forms within a blood vessel. If a thrombus breaks free and travels through the bloodstream, it has become an embolus. Providers may refer to a thrombus that has become an embolus as a thromboembolism or simply an embolism.

Detailed explanation-4: -A blood clot is also called a thrombus. The clot may stay in one spot (called thrombosis) or move through the body (called embolism or thromboembolism).

Detailed explanation-5: -An embolus is a particle that moves about in our blood vessels, either in the veins or arteries. Most emboli are composed of clotted blood cells. A blood clot is called a thrombus and a moving blood clot is called a thromboembolus.
