Intrinsic and extrinsic pathways of blood clotting are interlinked at the activation steps of which of the following factors?
Factor IX
Factor IV
Factor X
Factor XIIIa

Factor X
The blood coagulation cascade has 2 initial pathways that leads to fibrin formation. These are contact activation pathway (intrinsic pathway) and tissue factor pathway (extrinsic pathway) which both leads to fundamental reactions that produce fibrin. The pathways of mechanism of blood clotting are as follows:

Each 100 mL of human arterial blood carries 'P' mL of O2 and 'Q' mL of CO2, whereas each 100 mL of venous blood carries 'R' mL of O2 and 'S' mL of CO2. Choose the correct values of P, Q, R and S.
P =48 mL; Q=19 - 20 mL; R=52 mL; S = 14 - 15 ml
P= 19 - 20mL; Q= 48 mL; R= 14 - 15mL; S =52 mL
P = 14 - 15mL; Q = 52mL; R = 19 - 20 mL; S = 48mL
P = 52 mL; Q =14 - 15mL; R = 48 mL; S = 19 - 20 mL
