Final answer:
Tissue Factor Pathway Inhibitor (TFPI) is made in the liver and vascular endothelial cells. It inactivates the tissue factor pathway by inhibiting the activation of factor Xa and factor VIIa/tissue factor complex.
Step-by-step explanation:
Tissue Factor Pathway Inhibitor (TFPI) is produced in the liver and vascular endothelial cells. It functions to inactivate tissue factor pathway, specifically by inhibiting the activation of factor Xa and factor VIIa/tissue factor complex.
