Factor Xa, with Factor Va as a cofactor, turns factor II (also called prothrombin) into factor IIa or thrombin.

活性因子Xa和作为辅因子的因子Va将因子II（凝血酶原）转变为因子IIa（凝血酶）。

Tissue factor turns inactive factor VII into activate factor VIIa (a for active), and then tissue factor goes on to bind the newly formed factor VIIa to form a complex that turns factor X into active factor Xa.

组织因子使无活性的因子VII转变为活性因子VIIa，之后组织因子结合新形成的因子VIIa，形成一个复合物将因子X转变为活性因子Xa。
