003656. [edit on Wikidata] Bleeding time is a medical test done on someone to assess their platelets function. It involves making a patient bleed, then timing how long it takes for them to stop bleeding using a stopwatch or other suitable devices. The term template bleeding time is used when the test is performed to standardized parameters.
Ancient Greek painting on a vase, showing a physician (iatros) bleeding a patient. Bloodletting (or blood-letting) is the withdrawal of blood from a patient to prevent or cure illness and disease. Bloodletting, whether by a physician or by leeches, was based on an ancient system of medicine in which blood and other bodily fluids were regarded ...
Blood coagulation pathways in vivo showing the central role played by thrombin. Health. Beneficial. 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.
Platelet. Platelets or thrombocytes (from Ancient Greek θρόμβος (thrómbos) 'clot' and κύτος (kútos) 'cell') are a blood component whose function (along with the coagulation factors) is to react to bleeding from blood vessel injury by clumping, thereby initiating a blood clot. [1] Platelets have no cell nucleus; they are fragments ...
Hemostasis. In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. Hemostasis involves three major steps: vasoconstriction.
Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. [ 2 ]
A historical name for this measure is the kaolin-cephalin clotting time (KCCT), [1] reflecting kaolin and cephalin as materials historically used in the test. Apart from detecting abnormalities in blood clotting, [ 2 ] partial thromboplastin time is also used to monitor the treatment effect of heparin , a widely prescribed drug that reduces ...
The contemplation of the nine stages of a decaying corpse is a Buddhist meditational practice in which the practitioner imagines or observes the gradual decomposition of a dead body. Along with paṭikūlamanasikāra, this type of meditation is one of the two meditations on "the foul" or "unattractive" (aśubha). [1]: 24 The nine stages later ...
