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.
Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. [2] Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume).

Thrombosis (from Ancient Greek θρόμβωσις (thrómbōsis) 'clotting') is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss ...
In a small blood vessel, blood flow may be completely cut off (termed an occlusive thrombus), resulting in death of tissue supplied by that vessel. If a thrombus dislodges and becomes free-floating, it is considered an embolus. [citation needed] If an embolus becomes trapped within a blood vessel, it blocks blood flow and is termed as an ...
Blood transfusion also caused the transfer of platelets that can work along with coagulating factors for blood clotting to commence. [11] Different drugs can be prescribed depending on the type of disease. Vitamins (K, P and C) are essential in case of obstruction to walls of blood vessels.
The blood clot contains the secondary hemostasis plug with blood cells trapped in it. This is a necessary step for wound healing , but it has the ability to cause severe health problems if the thrombus becomes detached from the vessel wall and travels through the circulatory system; If it reaches the brain, heart or lungs it could lead to ...
Disseminated intravascular coagulation (DIC) is a condition in which blood clots form throughout the body, blocking small blood vessels. [1] Symptoms may include chest pain, shortness of breath, leg pain, problems speaking, or problems moving parts of the body. [1] As clotting factors and platelets are used up, bleeding may occur. [1]
Venous thrombosis is the blockage of a vein caused by a thrombus (blood clot). A common form of venous thrombosis is deep vein thrombosis (DVT), when a blood clot forms in the deep veins. If a thrombus breaks off and flows to the lungs to lodge there, it becomes a pulmonary embolism (PE), a blood clot in the
