Clotting cascade

Question 1

What is the first step in the intrinsic pathway?

Answer 1

12 -> 12a.
11 -> 11a
9 -> 9a
Then shared common pathway of 10 -> 10a.

Question 2

What is the second step in the intrinsic pathway?

Answer 2

12 -> 12a
11 -> 11a.
9 -> 9a.
Shared common pathway of 10 -> 10a.

Question 3

What is the third step of the instrinsic pathway?

Answer 3

12->12a
11->11a
9->9a
Shared common pathway of 10 -> 10a

Question 4

What is the common pathway shared between both instrinsic and extrinsic?

Answer 4

10->10a.

Question 5

What is the extrinsic pathway?

Answer 5

7 ->7a
Stimulated by tissue damage.
Then 7a stimulates 10->10a. This the common part.
