a process in which liquid blood is changed into a semisolid mass (a blood clot)

blood clotting involves numerous intricate chemical processes.

he said that there were many documented cases of plasmas being applied for sanitizing skin or other body parts, and 「for speeding the rate of blood clotting in wound healing.」

他表示说，利用等离子体为皮肤或人体其他部位消毒已有很多文献记载，「在伤口愈合时，它能加快血液凝固的速度。」

uniersity of chicago chemists hae demonstrated for the first time how to use a simple laboratory model consisting of only a few chemical reactions to predict when and where blood clotting will occur.

queen victoria and many of her descendants carried what was once called 「royal disease」—now known as hemophilia, a blood clotting disorder.

维多利亚女皇和她许多子孙后代携带有一度被称为「皇室病」的疾病——即现在的血友病，一种血液凝结的混乱癥。

at the site of an injury, blood clotting factors and other proteins interact in a chain of steps to form fibrin, which seals the wound and prevents further blood loss, as an mit news release explains.

据mit新闻稿报道，在伤口处，凝血因子和其他蛋白协调参与一系列反应，生成血纤蛋白。这种蛋白能愈合创面以防继续失血。

we think that the heart protection benefit from red wine is real, but is probably derived mostly from alcohol-induced higher hdl (」good') cholesterol, reduced blood clotting and reduced diabetes.

我们认为红酒确实可预防心脏病，但可能主要是因为酒精可提高含高密度脂蛋白（有益的）的胆固醇，进而减缓血液凝固并降低糖尿病的发病率。

healthy blood-making cells also congregate in special bone marrow niches, where they divide and make cells needed to fight infection, control blood clotting and carry oxygen to the body.

健康的造血细胞也集中在骨髓里特殊的处所中，在那里分裂和制造出抗感染，控制血凝和传输氧气所必须的血液细胞。

after a less-than-optimal operation, children sometimes experience a reduced capacity to perform physical activities and may experience blood clotting and ventricle arrhythmias.

it controls the balance between blood clotting and bleeding, and abnormalities affecting vwf can lead to health problems such as bleeding disorders and heart attacks.

它能够控制血凝出血平衡；对vwf有影响的异常状况能够导致诸如出血失调、心脏病等健康问题。
