Clotting [klot´ing] the formation of a jellylike substance over the ends or within the walls of a blood vessel, with resultant stoppage of the blood flow called also coagulation clotting is one of the natural defense mechanisms of the body when injury occurs a clot will usually form within 5 minutes after a blood vessel wall has been damaged the. Anatomy & physiology the circulatory system white blood cells fight infection and platelets help repair damage and clot the blood composition of blood platelets are disc shaped cell fragments which are involved in clotting the blood to prevent the excess loss of body fluids. Blood plasma is the yellow liquid in which blood cells float plasma is made up of nutrients, electrolytes ( salts ), gases , non-protein hormones, waste, lipids , and proteins these proteins are albumin , antibodies (also called immunoglobulins ), clotting factors, and protein hormones. Clotting (coagulation) time test although imprecise, the whole-blood clotting time test is one of the simplest methods to determine how well the clotting process is functioning this test determines how long it takes to initiate the intrinsic coagulation pathway after blood enters a glass tube.

Anything that interferes with the clotting mechanism of blood can cause abnormal bleeding the most common causes are platelet deficiency (thrombocytopenia) and deficits of some clotting factors, which can result from impaired liver function or genetic conditions such as hemophilia.
The liver, an organ only found in vertebrates, detoxifies various metabolites, synthesizes proteins, and produces biochemicals necessary for digestion in humans, it is located in the right upper quadrant of the abdomen, below the diaphragmits other roles in metabolism include the regulation of glycogen storage, decomposition of red blood cells and the production of hormones. Anatomy and physiology blood clotting cite blood clotting blood clotting can be initiated by the extrinsic mechanism, in which substances from damaged tissues are mixed with the blood, or by the intrinsic mechanism, in which the blood itself is traumatized. A blood clot is a thickened mass in the blood formed by tiny substances called platelets clots form to stop bleeding, such as at the site of cut but clots should not form when blood is moving through the body when clots form inside blood vessels or when blood has a tendency to clot too much, serious health problems can occur.

Clotting factors in the blood cause strands of blood-borne material, called fibrin, to stick together and seal the inside of the wound eventually, the cut blood vessel heals, and the blood clot dissolves after several days. When your blood vessels suffer damage, your body follows a sequence of events to promote blood clotting in this lesson, you will learn about coagulation cascade and important clotting factors.
Another good example of a positive feedback mechanism is blood clotting once a vessel is damaged, platelets start to cling to the injured site and release chemicals that attract more platelets the platelets continue to pile up and release chemicals until a clot is formed.

Blood anatomy blood is categorized as connective tissue it is in fact highly specialized and is created by formed elements these formed elements include erythrocytes, leukocytes, and platelets which are also known as thrombocytes these phospholipids activate the plasma’s blood clotting factors, creating what is commonly seen on the. Blood clotting (blood coagulation) the production of a mass of semisolid material at the site of an injury that closes the wound, helping to prevent further blood loss and bacterial invasion the clot is formed by the action of clotting factors and platelets. 211 anatomy of the lymphatic and immune systems 139 272 anatomy and physiology of the female reproductive system vascular spasm, the formation of a platelet plug, and coagulation (blood clotting) failure of any of these steps will result in hemorrhage—excessive bleeding vascular spasm.

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.
A blood clot is a coagulated mass of blood cells and other blood components it plugs any damaged area of the vessel wall and maintains the integrity of the blood vessel by preventing blood from leaking out.
