Question

You know that when you cut yourself, the blood flows out of the wound for only a short time. Then the cut is filled with a reddish solid material. This solid is called a blood clot. If blood did not clot, anyone with even a slight wound bleeds profusely.
i) Write the mechanism involved in coagulation of blood.
ii) What happens if blood coagulation does not occur when we meet with severe injuries ?​

Answer 1

Answer:

i) Blood coagulation is a process that changes circulating substances within the blood into an insoluble gel. The gel plugs leaks in blood vessels and stops the loss of blood. The process requires coagulation factors, calcium and phospholipids. The coagulation factors (proteins) are manufactured by the liver.

ii) A lack of clot formation can result in dangerous and excessive bleeding. Blood clots are the main way the body protects against blood loss from injured vessels. Two blood elements, platelets and fibrin, are the primary ingredients in blood clots.
