*for those who dont understand . Actually the video shows , hows the White Blood Cell fight against the bacteria once it comes to our body ! As we have known, one of the wbc functions is to fight against diseases soo the vidoe clearly show like the WBC engulf the bacteria . SUPER awesome ! this what i learnt during my bio lessons last monday . You can refer Biology text book form5 to get more information . BTW Whoever said BIO is boring , they're wrong ! :D

And , end of the class teacher asked a question which sound like this ;

" When the blood pressure is low , what happened and what can we make to make it rise to normal back ? "

answer ; An increase of blood pressure streches the baroreceptors . Impulses are sent to the cardiovaskular control centre in the medula oblongata of the brain . From there impulses are then sent via the parasymphathetic nerve to heart . This slows down the hearbeart , resulting in a decrease blood pressure . <--- Haram ta jawab macam nieh tadi -______-
