faint

Salam.
Hepi Thaipusam day people. :)
haihhh.. we had the day off today
Ohhh My.. Thank god.
Alhmdulilah... dah catch up circulatory system chapter.
"Brainachesymptom"
Aigooo~
Not yet entering immune system.

well, circulatory system is an interesting chapter though.
i'd get to know many facts 
from campbell. =)

U knw wat?
why we faint??
xtually, our blood pressure is affected by the gravity.
why a doctor usually take our blood pressure 
on our arm?
hehehehhee...
others than the reasons that there ia an artery there
this is also because our arm is at the same height as our heart.

then, faint happens when,
our head does'nt receive enough blood
due to the low blood pressure supply an unadequate
blood supply.
since our head is roughly 0.35m higher than our heart,
makes our blood pressure 25mmHG lower than in the same height 
at our heart.

Thus, when insufficient blood to our brain
we faint and collapse to the ground.
Why we collapse on the ground??

hehehehe...

we collapse to the ground to make our 
head at the same level as our heart.
when this happens, the blood will
flow quickly to our brain.

interesting rite? =)

MasyaAllah.... 

Thought reading campbell is a bit tough
but, i kinda like it sometimes
because there are things that we didnt think
why that happen.

and that is why  
"everything happens for a reason"

2 judgement:
