Coagulase-positive bacteria, like Staph aureus, convert the soluble fibrinogen into sticky fibrin, which then visibly clumps up.

凝固酶阳性细菌（如金黄色葡萄球菌）能将可溶性纤维原转化为粘性纤维，而出现肉眼可见的团聚现象。

The final step is activation of the protein fibrinogen to fibrin, which deposits and polymerizes to form a mesh around the platelets.

最后一是纤维原活化为纤维，聚集成网包小板。

The final step is activation of the protein fibrinogen (Factor I) to fibrin, which deposits and polymerizes to form a mesh around the platelets.

最后一是纤维原（因子I）激活转变为纤维，纤维沉积在小板上，并聚合形成网状。

The final reaction is the conversion of fibrinogen to threads of fibrin that trap blood cells and plasma to produce the clot.

最后的反应是将纤维原转化为纤维，捕获细胞和浆以产生凝块。

Thrombin then turns factor I or fibrinogen, which is soluble, into factor Ia or fibrin, which is insoluble and precipitates out of the blood at the site of injury.

之后凝酶将可溶的因子I（纤维原）转变为因子Ia（纤维原），纤维不可溶，便在损伤部位液中析出。

Plasma is the liquid part of the blood and consists of water, dissolved proteins, sugar, salts, hormones, and other substances. The four major plasma proteins are albumin, globulin, fibrinogen, and prothrombin.

浆是液的液体部分，由水，溶解的质，糖，盐，激素和其他物质组成。四种主要的浆是，球，纤维原和凝酶原。
