PATHOLOGY

Detailed explanation-1: -embolism – where the blood flow in an artery is blocked by a foreign body; this can be a blood clot or something else such as an air bubble.

Detailed explanation-2: -Thrombosis is the formation of a blood clot (thrombus) inside one of your blood vessels or a chamber of your heart. Clots can block blood flow in your blood vessels or break free and travel elsewhere in your body.

Detailed explanation-3: -Platelet factors As platelets accumulate at the site, they form a mesh that plugs the injury. The platelets change shape from round to spiny, and they release proteins and other substances that entrap more platelets and clotting proteins in the enlarging plug that becomes a blood clot.
