血型問題 蚊子

2012-10-10 1:55 am
不同血型的血液混合在一起會有可能導致凝血、溶血等現象,而如果這發生在人體上,就有可能危及其性命。那麽,為何蚊子在吸取不同人的血液後,又不會產生以上的視象呢?

✔ 最佳答案
Firstly the mosquito uses an anti-coagulant,to stop clotting occurring. (I am aware that technically coagulation and agglutination are quite different things).
Secondly the mosquito can only drink one type of blood at a time. So even if they go onto another host moments later , the first lot has already started being metabolised.You have to remember the blood is being digested.
Whether agglutination occurs is hard to say .But it's unlikely ,though if it does ,it isn't enough to disrupt or hinder the processing of the food source.
This is a rudimentary survival necessity. As mosquitoes rely on blood protein for reproduction.
They've evolved to deal with various obstacles in their way.

閣下胃中的食物都是固體, 不會危及性命, 因為是在胃不是在血管嘛!!

血液到蚊子肚裡, 是否凝結也不會阻塞而對蚊子造成任何傷害, 反正有消化酶, 固體液體食物也無妨. 血細胞本來就要消化掉, 溶血不是有助消化嘛?

你的問題好奇怪喔.

我認為可能佢有一個專裝血的袋卦
