How about the term hemostasis, do you know what this mean or when this term generally used? If you’re not familiar in this term, please take note in the following details that I will mention here.
The term hemostasis (or haemostasis and the opposite is hemorrhage) is describe as a process of stopping the bleeding or to keep blood within a damaged blood vessel. In most cases, this process includes blood changing from liquid to solid state. In other reference says that the unbroken blood vessels are central to control blood’s tendency to congeal. And it adds, that the intact blood vessels has endothelial cells that helps to prevent blood clotting with a heparin-like molecule and thrombomodulin, and it prevent platelet aggregation with nitric oxide and prostacyclin.
There are three major steps that are involved in hemostasis process, these are, and vasoconstrictive, temporary blockage of a break by a platelet plug and blood cluttered or formation of a clot that seals the hole until tissues are repaired. To help us understand these three mechanisms, let’s consider another reference says in this regard. Here as follows:
In vasoconstrictive the paracrine was released by endothelium and temporarily decreases blood flow and pressure within the vessel. After that, temporary blockage will follow. This process is used to block the hole by a platelet plug, form as platelets stick to exposed collagen and become activated and release cytokines into injured area. And the third step is the coagulation cascade, a series of enzymatic reactions that will ends the formation of a fibrin protein fiber mesh that stabilizes the platelet plug.
