问题血小板是如何参与生理性止血的?

选项

答案

解析血小板被激活通过黏附、聚集、释放等反应参与生理性止血。在释放ADP的基础上形成血小板止血栓(初步止血)；参与启动凝血过程以促进血凝块形成(有效止血)；同时释放5-羟色胺、血栓烷A使血管收缩以助止血。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
