the heart pumps but the brain give it signals to pump, so apart from d pumping of blood what else does the heart does?

mfm04622:

So does the brain stop working when you sleep? Without the brain, your heart CANNOT work!

freecocoa:
If the brain lives on after the heart stops, how did that happen? Did the heart not have to pump blood to the brain for the brain to be alive? If the brain keeps living after the heart stops for a minute, then it is living on what the heart fed it, if the heart doesn't come back on, the brain is gone forever, so the brain needs the heart to keep feeding it for it to function.

ILIDEFI:


The heart doesn't receive signal for it's activity from the brain. The heart has what is called SA node which generates impulses for it's contraction. The brain only works to either speed up the beat or slow it down depending on other prevailing circumstances. So between the brain and d heart directly, d heart doesn't need d brain to work. But if d heart stops beating for more than 5mins, d brain and the whole body is gone.

Lol...Oya show me my ignorance with facts na. I'll try to be polite next time ...guess someone insulted me while quoting me and set me off on an insulting spree.

The nose
All other rest except the nose.

The nose is the anchor of life.

If you close your mouth and nose for a minute, will you die ? No but you will start grasping for air.

What happens is that your heart keeps recycling deoxygenated blood throughout your body and when it keeps getting to the brain, it sends message to your hand to remove it from your respiaratory organs.

During that period you closed your respiratory organs, the laziness of the heart becomes exposes because it is carring in and taking away same blood without air to the body system until the brain comes to its rescue.

I'm not undermining the importance of the heart but to put it at par with the brain is a great disservice to the functionality of the brain.

AlphaDray:
prof. What keeps the body alive, is it the brain, the heart or The air we breath? Cos it Seems Like you've forgotten the nose and I also know the body, that includes the brain and the heart need air

The second question is, where does air pass thru?

You don't need a nose to breathe. The mouth can do the work perfectly.

The first organ to develop in an embryo is d busiest,the heart is the busiest.the heart pumps blood first before the brain takes over.

Djicemob:

A.The brain
B.The Eyes
C.The Nose
D.The Ears
E.The Heart
F.The Mouth

Pls choose and state your reasons

The human brain cos its responsible 4 all the work in the body including the heart,the heart is jiust to pump blood

do you know how important that pumping of blood is?? Do you realize you are dead once the pumping stops?? Did you know the brain rests when you're sleeping?? That is what causes sleep-walking, the body is awake but the brain is still in sleep state. Bottomline: The heart is the most important and most hardworking organ

AlphaDray:
the mouth has purpose which for eating, drinking just A few. Now including breathing as its perfect work. Man you wicked!! God who gave us nose and mouth is no fool...ok? Dude u r a case

You guys should stop misleading people. If the brain doesn't control the heart, what then is the function of the medulla oblongata ?

Nice...but before I clap for you let's not forget what this thread was all about. Which part of the body listed in most hard working and which one can't we do without. I believe we can comfortably live with an artificial heart...but you cannot live without a brain. The heart only pumps blood as it's single function whereas the brain does a whole lot more. The brain wins on all levels.

freecocoa:
Gasping for air is as a result of the heart trying to function properly, if the heart gasps for air and couldn't get it, there will be no activity in the brain.

mfm04622:


Where did you get that info? What do you dream with? Your heart? What control your heart when you sleep? Or your breathing? Or you think those organs work on automatic?

Soknown:

Prof ke ?. I attended a workshop and I got talking with another participant that is very good in mountain hiking an all that. He mentioned of a particular incident that he needed to drill a hole in the throat of another climber who couldn't breathe before the chopper rescue came, in that instance the guy was able to breath without the use of the nose or nostrils, you can breath through your mouth or a hole though the throat.

ILIDEFI:


Read my post again. I said d heart generates its impulses and beats by itself. What is misleading there?

WIZGUY69:
brain.


modified : I wanted to chose the heart, but I remember that researchers said that when you sneezes, the heart stop working for some seconds, so its definitely the brain.

even while sleeping, the neurones are sent to the brain to check if one's alive.

if the neurones are are sent to somewhere else, then the Person will die from sleep.

Op asked for the one that doesn't rest, busiest and most hardworking, not the most important.

Now check out this link:
en.m.wikipedia.org/wiki/Brain_death

Take note of this statement:

"Note that brain electrical activity can stop completely, or drop to such a low level as to be undetectable with most equipment. An EEG will therefore be flat, though this is sometimes also observed during deep anesthesia or cardiac arrest."

Nawa for you o.

This is where you guys exaggerated the function of the heart thinking it recognises the air in the blood. All it does is pump oxgenated blood through the arteries and deoxgenated through the vein using the chambers of the heart.

While you grasp for air, your heart is working perfectly well until the oxygen is your blood is used up and the brain seek for help. It is your brain that recognises that there is no oxygen in your blood at that moment not even the heart carrying it !

This is why I ask you that beside pumping of blood, what else does the heart does ? Nothing !
