Haemostasis ( Coagulation and Fibrinolysis )
Monday, 9 October 2017
Hi and Assalamualaikum 😊
Today we would like to share with you about Blood Hemostasis!Do you know what means by haemostasis? Is it haemostasis has same meaning with homeostasis?😏Haemostasis is defined as stopping of bleeding from the blood vessels. However, homeostasis is defined as the tendency towards a relatively stable equilibrium between interdependent elements of the human body.
HEMOSTASIS.....
BLOOD CLOTHING PROCESS
A blood vessel is injured
The walls of the blood vessel contract to limit the flow of blood to the damaged area
Small blood cells called platelets stick to the site of injury and spread along the surface of the blood vessel to stop the bleeding.chemical signals are released from small sacs inside the platelets that attract other cells to the area and make them clump together to form what is called a platelet plug.
On the surface of these activated platelets, many different clotting factors work together in a series of complex chemical reactions (known as the coagulation cascade) to form a fibrin clot. The clot acts like a mesh to stop the bleeding.
Blood Clotting Summary
1) COAGULATION CASCADE 🐦
The coagulation cascade is classified into three pathways the extrinsic pathway, the intrinsic pathway, and the common pathway.
2) FIBRINOLYSIS
