Now no matter what other organs do, without the blood that is being pumped, they can't function, oxygenated o deoxygenated o, there needs to be a blood flow, which enables other organs work. I honestly don't get why we are still having this talk.

Because you believe the heart is on autodrive and doesn't need instruction from the brain to function.

Bluetooth2:


You said the brain doesn't control the heart and I asked you what is the function of the medulla oblongata. The heart doesn't generate any beat by itself because that that of the brain regulates heartbeate and breathing.

Medulla works through the vagus nerve to moderate heart rate, so that the sympathetic firing from the hypothalamus won't make the heart go hay wire. But still yet, the heart initiates it's rhythm by itself. As for respiration, it's different cos the brain totally controls it.

It's proven that it pretty much doesn't need the brain to function, if a person is not existing without his brain, there won't be any need to hope he recovers brain activities, he would have just been pronounced dead and forgotten.

The brain doesn't rest, it is always busy and it is the most hard working because it does the most work. Now let me ask you, between a water pump and a computer , which one is doing more work...


In relation to brain death why didn't you post everything..
Brain death is the complete and irreversible loss of brain function (including involuntary activity necessary to sustain life).[1][2][3][4] Brain death is one of the two ways of determination of death, according to the Uniform Determination of Death Actof the United States (the other way of determining death being "irreversible cessation of circulatory and respiratory functions".[5] It is not the same as persistent vegetative state, in which the person is "alive".

Brain death is used as an indicator of legal death in many jurisdictions, but it isdefined inconsistently. Various parts of the brain may keep living when others die, and the term "brain death" has been used to refer to various combinations. For example, although a major medical dictionary[which?] says that "brain death" is synonymous with "cerebral death" (death of the cerebrum), the US National Library of Medicine Medical Subject Headings (MeSH) system defines brain death as including the brainstem. The distinctions can be important because, for example, in someone with a dead cerebrum but a living brainstem, the heartbeat and ventilation can continue unaided, whereas in whole-brain death (which includes brain stem death), only life support equipment would keep those functions going. Patients classified as brain-dead can have their organs surgically removed for organ donation.

Thanks.

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

I tot the heart also send blood to the brain. The duo work concurrently.

BlackPeni5:
Na lie o...Na brain. The brain Controls and coordinates all aspects of the body. If you brain stops working everything else stops. If your heart stops, you don get heart attack be that but you may not die. There can be a heart transplant but we never hear of brain transplant before o.

Most importantly...you are not alive because your heart is beating or because you can breathe through your nose. You are alive because your brain tells your nose to breathe and your blood absorbs the oxygen and the brain then tells the heart to pump the oxygenated blood to the parts of the body which it is needed. The brain is the master key.

Some people quoted me saying there have been a successful brain transplant and I asked them to provide the source or link to the info...another said the body can function without the brain and gave an example of persons who are brain dead but still alive. I clarified that, persons that are brain dead are usually on life support and the machine tries to do the work of the brain by keeping the organs working. Once its switched off, the person dies. Another said the heart is always pumping and I made them understand that there are many people who use pace makers which are electronic hearts. They do not beat but still pump blood. The heart has only one function which even it is not in charge of while the brain does multiple tasks. I dont know if anyone posting here is using his heart to reason and post on Nairaland. Simply because you can hear the heart beat does not mean that the most hard working...remember that empty vessels make the largest noise.

wtf..nigga is just teaching us biology

Op asked for the one that doesn't rest, is the busiest and most hardworking, and not the most important or the one we can't do without.
Considering his question, I give it to the heart.

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."

Let's talk about being hard-working. What does the heart do, it receives blood from veins through-out the body send blood to the lungs for oxygen, send blood to the liver to receive glucose and other things and pump to all part of the body, it does this 24/7 non-stop( broadly speaking) through-out lifetime.
What does the brain do, it receives impulses from all parts of the body, process the information, interprets and send information back to the body or store them as the case may be. Can we count how many impulses ( internal and external) the brain gets and process every seconds of the day. It does all these seamlessly through-out lifetime. Honestly with all the Million terabyte of information processed and possessed by the brain. and as I said earlier it lives longer than the heart. #Brain all the way.

Thanks.

Well spoken, but ur 1st paragraph cught my attention, water has nothing to do with a computer system, they re not in the same body.

While the transplant goes on, is their something used to replace it to enable one stay alive?

Yeah, depending on the method (orthotopic procedure), the use of a cardiopulmonary bypass machine may be employed

At this time, the Heart does nothing but to pump blood.... Where the heart comes in is "if I verbally attack anyone's Comment.

hmmm you av a big point there! But d heart is the Boss. The heart communicates to the brain and the body in four ways including: 1) nervous system connections, 2) hormones produced in the heart itself, 3) biomechanical information via blood pressure waves, and 4) energetic information from the strong electrical and electromagnetic fields. The fact that the heart produces hormones released into the blood stream affecting all of the body was first demonstrated 30 years ago and has led to tests routinely performed in hospitals across the country

Even this is subjective, the blood as we know it does really reach the brain as blood, it's just the constituents, glucose, oxygen and amino acid that reach the brain cells.

Brain doesn't control heart. You transfer from your heart to your brain which mean without heart help brain is not functioning. [color=#000099][/color][b][/b]

Thanks, it was just an analogy. I quoted BlackPen' though. it was his post.

Because unlike the heart, there is no such procedure for the brain.

Oh? I was just talking about the relative sacredness (for lack of a better word) of the brain in comparison to the heart.

The premise of this thread isn't even clear to begin with. How do we define "rest" in this context?
I wasn't taking a stab at the topic lol

The heart..

very technical, all of them are always very busy.

if you say the mouth is less busy when we are asleep, what about pple who do snore

Ever heard of BRAINDEATH?
The moment your brain stops, mehn it's over for u
Meanwhile the brain controls all

There is something called brain death. Someone can be brain dead and still be alive, just that he/she won't be able to do anything. The heart will still be working as long as they can keep paying the hospital bills
On the other hand, once a heart stops, everything else stops.

It is the brain!!!! The brain happens to be the most underrated part of the human anatomy. It contains about 15-33 billion neurons. It is the CNS of the body(central nervous system). inside the brain, is the hypothalamus which controls the heartbeat, without it, the heart is just a piece of meat. The brain uses about 40percent of the oxygen and glucose gotten from metabolic reaction in the body. That's why once there's lack of glucose or oxygen, the brain immediately hibernates the body so as to reduce the absorption of the less remaining glucose. The brain is in charge of hormonal and enzymic release in the body, when you talk of estrogen, progestorone, oxytocin, insulin, testorone etc you are referring to the brain bcus it controls, secrete and reduces them in the body. For example when you consume excess sugar, the brain releases insulin which acts against the glucose and converts them to glycogen which are then stored either in the liver or mucles. If you have no brains, the glucose will remain in the blood stream which will make you suspectible to Mellitus(Diabetes). My dear friend the functions of the brain goes on and on. The main one sef is for you to reason.. LOL. Brain=Hypothalamus+Thalamus+Grey matter+ Frontal lobe+Cerebellum+Medulla+Olfactory nerve. Synthetic heart has been replicated in various forms and are used for patients with heart defect but the brain can nevr and will never be replicated not till another 20,000 years of research. Food for thought: when you sleep! What controls your heart to keep beating?

The heart. Because once it stops beating,the person dies.

Point of correction brother: the brain functions on oxygen and glucose only.. In all creation none of them uses blood for brain function with the exception of insect, they use lymphatic substances. The brain is the chief of the body. It controls the heart to beat...

I agree with you totally sire, the brain remains the GCFR of the body. Brain transplant has never been carried out anywhere in this world in the last 10years. I have it on authority as a Med student. The only procedures been done is called a craniotomy which involves either scraping parts of the brain where they are dead cells or inserting a pacemaker to send electrical impulses to a section of the brain. Most people underrate the brain, it's a sad fact. Brain transplant has been done in years and can't, not till after 20,000 years of research. If technology can achieve that feat then we would unlock one of the worlds hidden secrets.
