The path of blood through the heart begins with the right atrium receiving blood, which has circulated through most of the body. This blood is relatively low in oxygen because most of it has already been delivered to different organs and tissues.
Tissue factor pathway inhibitor (TFPI) inhibits a complex that starts the process of clotting. Most of TFPI (60% â 80%) is bound to the lining of the blood vessels (endothelium), with only 20% free in the blood. Recent evidence suggests that low levels of TFPI are a risk factor for clotting disorders.
