haemostasis

Haemostasis Introduction: Haemostasis is a process that prevents excessive fund neediness give the body. Most times this includes turning the breed from a liquid to a solid state. There ar triad main processes the body goes through during haemostasis to contorol bleeding, these include, vascular cramp, thrombocyte plug, and telephone line clotting. vascular spasm: Vascular spasm occurs when a blood vessel is punctured. The vessels muscle contracts and wampum blood supply to the punctured vessel. This occurance can be seen as the bodies form of first aid, the body can hold this for minutes or even hours. The vasular spasm happens because of the pain receptors in the body, which count a craps the muscles contract. blood thrombocyte wad Formation: Platelet plug formation has three stages contrasted the process of Vascular spasms. These three stages include: Platelet attachment - The first microscope stage begins when platelets expose damage to a blood ve ssel and begin to stick to the exposed surfaces. Platelet come out reaction - This phase is when the platelets call ons granules to asist with the clotting process. This is the stage that stimulates the the process of make a paltelet work, its a very important stage of qualification platelet plugs.

Firstly the platelets create extentions so that they can get to for each one other, then they are able to give away in that reward contents. There are two types of granules held within the cytoplasm of platelets: important granules that contain clotting factors, growth factors, and fibroblasts, and dense granul es that contain ADP, ATP, atomic number 20 ! ions, and Serotonin. Other components are also present within the platelet that assists the process. Nearby platelets are stimulated into action by the release of ADP and other chemicals. Platelet aggregation - The ADP acts to make the nearby platelets sticky and stick to the other platelets. When the collection of platelets is giant enough it creates a platelet plug stopping the mischief of blood through holes in small vessels.
