When should you worry about blood clots during your period? Menstrual bleeding that lasts more than seven days, known as menorrhagia , can be a signal of a larger health issue.
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It results in hemostasis , the cessation of blood loss from a damaged vessel, followed by repair.
In light transmission aggregometry (LTA), platelet-rich plasma is placed between a light source and a photocell. Unaggregated plasma allows relatively little light to pass through. After adding an agonist, the platelets aggregate, increasing light transmission, which is detected by a photocell. [56]
A thrombus (pl. thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis.There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein.
Diagram illustrating how the uterus lining builds up and breaks down during the menstrual cycle Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone ...
Thus, a fibrin mesh is produced all around the platelet plug to hold it in place; this step is called secondary hemostasis. During this process some red and white blood cells are trapped in the mesh which causes the primary hemostasis plug to become harder: the resultant plug is called a thrombus or blood clot. The blood clot contains the ...

Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus. [1] [2] Thrombosis may occur in veins (venous thrombosis) or in arteries (arterial thrombosis).
