AHA!

Have you ever wonder
why our body sweat

when body temperature

There are 3 main
events that occur in
our body when we run

Hair follicle Pumping of heart Blood vessel

Hypothalamus sending impulses
to efector muscle

Impulses

OMG! There she Impulses
goes with her
facts. Its okay. I'll make
it fun.

If we become This reminds me
too cold, the of my favourite

Oh...

Thinking back to 2019, there was a
regatta competition held in Kuching,
Sarawak and team Landas was able
to reclaim their 'Raja Sungai' title.

Next, let's move
on to the pumping
of heart

GO LANDAS GO

WOOO !!

The competition was Uwu, that's interesting !
pretty fierce and I wish i could be there
exciting to watch on too.

*Uwu= an expression of amazement
Eh, wait. I think I know
why team Landas had won Don't tell me Hmm..
the competition that they cheated
time.

Why so ?

Eh, no lah. No way ! It must be the
drummer !

DUM

Let's get back to the topic. It has the same

The faster the beating
is, the faster the blood

When heart beats faster and O2

Hence, making oxygen can be

This explains why you could run
faster and does not faint
immediately after you start to
run.

Now, let's move to When the body is too hot,
the third point. blood vessels under the
skin will dilate.

The blood This process is known as
is shunted vasolidation.

toward This way more heat is radiated away
the surface. from the body.

Do you want to know what The blood vessels at surface

cold ? and move further
from the skin
surface.

This process is known as
vasoconstriction.

We can relate these processes to the before and
after

Before After

Imagine the red blood cells

cars move inefficiently on a more cars can move efficiently on a
narrow road. wider road.

the blood vessel Same goes to our blood vessels,

Skin surface

less blood flow more blood flow

harder heat to escape from

the surface of the skin.
easier heat to escape from

that`s it BRILLIANT I
hehehe THOUGH!! UNDERSTAND !

GUYS ! WOW ,
LOOK AMAZING

ITS ITS A
