SCRIPT ON HAEMOSTASIS
Introduction:
Haemostasis is one of the metabolic processes that are associated with many changes
in the body and hence it has been the topic of extensive research for a considerable amount of
time (Key, 2017). In this presentation I would be focusing on the haemostasis mechanism and
the factors associated with the procedure.
Explanation of task concept:
First and foremost, I would like to address the importance of my choice of this topic
for this digital media presentation. I would like to draw your attention to the fact that
haemostasis is the process that causes bleeding to stop in the body. This is the process which
gradually changes the liquid state to solid state during and after the process of clotting. There
are 13 different clotting factors involved with the entire process and along with that there is
an intricate physiological and genetic network which plays fundamental roles in the process
of haemostasis (Monagle, 2015).
Process:
In this slide, I would like to mention that this natural process of blood coagulation
during the time of an injury leading to breaking of skin and bleeding involves three
interconnected steps. The steps are vascular spasm or vasoconstriction, followed by
formation of the platelet plug and then the last step which is the coagulation. Exploring the
issue further, the first step is the vasoconstriction, which is a reflex step where the blood
vessels present in the injury site is narrowed down and as a result to increase blood pressure
(Panteleev, Dashkevich & Ataullakhanov, 2015). The process is initiated by the local
sympathetic pain receptors which triggers vascular endothelium which releases intravascular
signals to the smooth muscle cells for the contraction to begin. This leads to collagen to be
exposed which triggers the platelets to adhere to the injury site.
