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.
QWERTY, one of the few native English words with Q not followed by U, is derived from the first six letters of a standard keyboard layout. In English, the letter Q is almost always followed immediately by the letter U, e.g. quiz, quarry, question, squirrel. However, there are some exceptions.
Coagulative necrosis is most commonly caused by conditions that do not involve severe trauma, toxins or an acute or chronic immune response.The lack of oxygen (hypoxia) causes cell death in a localized area which is perfused by blood vessels failing to deliver primarily oxygen, but also other important nutrients.
Coagulation is the process by which blood forms clots.. Coagulation may also refer to: . Coagulation (water treatment), in colloid chemistry, a process in which dispersed colloidal particles agglomerate
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
After centrifugation, one can distinguish a layer of clear fluid (the plasma), a layer of red fluid containing erythrocytes, and a thin layer in between.Composing less than 1% of the total volume of the blood sample, the buffy coat (so-called because it is usually buff in hue), contains most of the leukocytes and thrombocytes.
Hemorheology, also spelled haemorheology (haemo from Greek ‘αἷμα, haima 'blood'; and rheology, from Greek ῥέω rhéō, 'flow' and -λoγία, -logia 'study of'), or blood rheology, is the study of flow properties of blood and its elements of plasma and cells.
Global tests, also known as global coagulation assays (GCAs), [1] characterize the results of work of the whole clotting cascade. They suit to diagnose the general state of the blood coagulation system and the intensity of pathologies, and to simultaneously record all attendant influences.
