And then they have these specially adapted, very sharp teeth which cut as they bite, and then they actually have an anticoagulant, and that helps it to continue bleeding freely.

然后，它们用其这些特异适应、极其锋利牙齿，在咬住猎物同时将其（皮肤）切开，并且它们（唾液中）自带种凝血剂，能使血液不断流出。

In 1916, a pair of American scientists found an even more effective anticoagulant called heparin, which works by deactivating enzymes that enable clotting.

1916 年，国科学家发了种更有凝血剂，叫做肝素，它通过使可凝血酶失活而发挥作用。

Mosquito saliva is an anticoagulant, meaning it prevents blood-clotting, allowing blood to travel smoothly and efficiently from person to mosquito.

蚊子唾液是种凝血剂，意味着它可以防止血液凝固，使血液在人与蚊子之间顺畅有地流动。

They can be treated successfully with blood thinners, but these carry risks.

它们可以通过使用凝血剂成功治疗，但这些药物存在风险。

When a mosquito bites you, it releases a compound into your body called an anticoagulant that prevents your blood from clotting.

当蚊子叮咬你时，它会向你体内释放种名为凝血剂化合物，以阻止血液凝结。

It resembles a condition known as heparin-induced thrombotic thrombocytopenia, which occurs occasionally with the blood-thinner heparin.

它类似于种被称为肝素诱导血栓性血小板减少症病症，这种病症偶尔会在使用凝血剂肝素时发生。
