Answer 2

Causes the smooth muscle of the blood vessel to contract. This narrows the blood vessels, cutting off the blood flow to the damaged area

Question 3

What is thromboplastin

Answer 3

Enzyme that sets in progress a cascade of events that leads to the formation of a clot

Question 4

The blood clotting cascade 1/4

Answer 4

Platelets form a plug and release clotting factors including thromplastin

Question 5

The blood clotting cascade 2/4

Answer 5

Prothrombin is changed to its active form thrombin, catalysed by thromplastin

Question 6

The blood clotting cascade 3/4

Answer 6

Thrombin acts on soluble fibrogen converting it to insoluble fibrin. This forms a mesh to cover the wound

Question 7

the blood clotting cascaded 4/4

Answer 7

Platelets and blood cells become trapped in the fibrin mesh forming a blood clot and a scab

Question 8

The blood clotting cascade 5/5

Answer 8

Calcium and vitamin K is essentially required for the progression and acceleration for the blood coagulation process

Question 9

What is a platelet

Answer 9

cell fragement that releases thromplastin

Question 10
