coagulation, in physiology, the process by which a blood clot is formed. The formation of a clot is often referred to as secondary hemostasis, because it forms the second stage in the process of arresting the loss of blood from a ruptured vessel.
What is coagulation and what is its function?
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair.
What is coagulation and example?
Definition of ‘coagulation’ Coagulation involves the formation of a blood clot, which prevents further blood loss from a wound. Coagulation is the process of changing from a liquid to a gel or solid, for example, the process that results in the formation of a blood clot.
What is called coagulant?
Coagulation: In medicine, the clotting of blood. The process by which the blood clots to form solid masses, or clots. More than 30 types of cells and substances in blood affect clotting.
What are the 4 steps of coagulation?
1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.
What is the difference between coagulation and clotting?
Coagulation (or clotting) is the process through which blood changes from a liquid and becomes thicker, like a gel. Coagulation is part of a larger process called hemostasis, which is the way that the body makes bleeding stop when it needs to.
Why is coagulation important?
Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
What causes coagulation?
Blood vessels shrink so that less blood will leak out. Tiny cells in the blood called platelets stick together around the wound to patch the leak. Blood proteins and platelets come together and form what is known as a fibrin clot. The clot acts like a mesh to stop the bleeding.
What is another word for coagulation?

What is the best definition of coagulation?
Definition of coagulation : the process of becoming viscous or thickened into a coherent mass : the forming of clots (as in blood or cream) : the process of coagulating … an incision is made on the skin of the forearm with a spring-loaded device, and the time to coagulation is measured.—
What are the method of coagulation?
There are a number of different methods employed including clot-based coagulation tests, chromogenic assays, immunological tests, and aggregation studies. Today automated machines are designed to be able to perform a number of different methodologies.
What are the types of coagulant?
- Aluminium coagulants – e.g. aluminium sulphate, aluminium chloride and sodium aluminate.
- Iron coagulants – e.g. ferric sulphate, ferrous sulphate, ferric chloride and ferric chloride sulphate.
What is coagulant made of?
Chemicals commonly used for primary coagulants include aluminum or iron salts and organic polymers. The most common aluminum salt used for coagulation is aluminum sulfate, or alum. Alum may react in different ways to achieve coagulation.
What are the 3 coagulation pathways?
Coagulation consists of three pathways, the extrinsic, intrinsic, and common pathways, that interact together to form a stable blood clot. The extrinsic and intrinsic coagulation pathways both lead into the final common pathway by independently activating factor X.
What are the 13 clotting factors?
- Factor I – fibrinogen.
- Factor II – prothrombin.
- Factor III – tissue thromboplastin (tissue factor)
- Factor IV – ionized calcium ( Ca++ )
- Factor V – labile factor or proaccelerin.
- Factor VI – unassigned.
- Factor VII – stable factor or proconvertin.
What are the two basic stages of blood coagulation?
The clotting cascade occurs through two separate pathways that interact, the intrinsic and the extrinsic pathway. The extrinsic pathway is activated by external trauma that causes blood to escape from the vascular system. This pathway is quicker than the intrinsic pathway.
What causes coagulation problems?
Coagulation disorders cause the body to form too many or too few blood clots. They are usually due to a genetic mutation and are often treatable with medications. Coagulation disorders can cause excessive bleeding if the body is unable to form blood clots properly.
What happens if the blood does not coagulate?
Overview. Hemophilia is a rare disorder in which the blood doesn’t clot in the typical way because it doesn’t have enough blood-clotting proteins (clotting factors). If you have hemophilia, you might bleed for a longer time after an injury than you would if your blood clotted properly.
What prevents coagulation?
All our blood vessels are lined with a layer of specialized cells called endothelial cells. This monolayer of cells is called endothelium, and one of its jobs is to prevent unwanted blood coagulation.
What are coagulation disorders?
Coagulations disorders are conditions that affect the blood’s clotting activities. Hemophilia, Von Willebrand disease, clotting factor deficiencies, hypercoagulable states and deep venous thrombosis are all coagulations disorders.
What is the scientific name for blood clotting?
Thrombus… The medical term for a blood clot.
What is the use of coagulant?
Coagulants and flocculation processes are used to remove colloidal impurities: suspended particles such as bacteria, clay, silts, and organic matter from the contaminated water. This produces large flock aggregates that can be removed from the water in subsequent clarification/filtration processes.
What is the opposite of blood clotting?
A thrombus is a blood clot that occurs in and occludes a vein while a blood clot forms within an artery or vein and it can break off and travel to the heart or lungs, causing a medical emergency.
What is the most common used coagulant?
Iron and aluminium salts are the most widely used coagulants but salts of other metals such as titanium and zirconium have been found to be highly effective as well.
What is removed during coagulation?
What Is Removed During Coagulation? Coagulation is most effective at removing suspended solids and natural organic matter like gravel, sand, algae, clay, iron, protozoa, and even bacteria.
