Which dies first  the brain or the heart  ?

The brain starts slowing down first, and it tells the heart to slow down too. so technically, the brain quits first and when the heart stops recieving messages to beat, it stops too.

death is physical\nsoul never dies it always sustain\nand soul is like a part of god and it is always remain inside a human to direct him in a right path but its all the brain of human who took decision

Hello Summerspirit,\n\nThanks for your question. I think this question deserved a better reponse than what it has received till now. Anyways, I'll try to compensate: \n\nFirst of all, neurons don't usually die at all. The neurons are the cells with the least regenerative powers in our body. Once killed, they cannot be replaced! But, as we grow older, some wear and tear is unavoidable and brain cells too are no exception to the wear and tear of ageing. \n\nStill, the brain cells are the last to die in our bodies as they are kept well oxygenated by an abundant blood supply.\n\nNow, the neuroglia cells that support the neurons are not as sustainable as the neurons and thus, are subject to regular wear and tear. So, there must be a path for them and other metabolic wastes to leave the brain, right? \n\nOur brain as opposed to popular conception is not a lump of matter floating in blood. It is floating alright but, not directly in blood. The brain floats in a colorless, transparent, plasma-like fluid called Cerebro-Spinal Fluid or CSF. The fluid provides a one way traffic from the cavities and membranes of the brain to the vein carrying used blood.\n\nSo, the CSF takes the dead brain-cells and flows towards a blood stream, then the waste matter is transferred to the blood.\n\nThe blood then takes the stuff to the kidneys which is known as the sieve of the human body. Kidney filters the metabolic waste from the blood to urine from where it is passed from the body.\n\nHope it helped to keep your summer spirit alive! Bye!

That's not true.  The brain gets the biggest hit.  That's why they're called EMOTIONAL.  As far as the other organs, you have to define how you measure "effect".  That is, everything gets kicked a little during an emotional wave, adrenals, muscles (including the heart), circulatory system, etc.  Just because the heart rate is the easiest to detect does not necessarily mean that it gets a bigger jolt than anything else.

The heart is more important.

I believe that brain activity is the definition of death. Even if the heart and lungs have shut down, as long as there is brain activity, the doctors don't consider them dead and will work to revive them. However, if there is no brain activity, they won't.

because the body cannot live without BRAIN

A) Cell bodies is my choice.\n\nCerebral cortex  is a thin, convoluted surface of the brain consisting mainly of nerve cell bodies.♥

The basic heartbeat is controlled by cells in the heart which have leaky membranes-Ions leak in, and depolarize the cell, which then causes a rapid spreading contraction.  Thus, the brain does not control basal heartrate.  The brain, through mediation of the sympathetic and parasympathetic nervous system can, however, modulate the rate of the heartbeat.  There are some specific loci which are associated with these systems, but the most potent is the emotive centers of the brain, which in turn are regulated by the cerebral cortex (the "thinking" part of your brain), which is why, when you are told you just flunked a test, your heartbeat rises, while when you listen to relaxing music, your heartbeat slows.  The conscious part of your mind sends signals to the emotive centers, which then regulate the symapthetic and parasympathetic system.  But, cutting off your head will not stop your heart from beating...at least not until the heart itself runs out of oxygen because of the lack of breathing.

The brain is an organ of the body, like any other organ, in that it has a distinctive structure and tissue types specific to the brain.  Thus, it is a biological entity.  Psychology is a study of our mental processes and behaviour, not the actual biology of the brain organ.

the heart generates its own electrical impulses to stimulate the heart to beat . It is the SA node in the atria and the AV node in the ventricles. \n\nWhen patients have been diagnosed as brain dead - and on a ventilator ( a breathing machine )  - their heart is still beating - because the heart has its own built-in battery pack, so to speak .

The brain is not part of the circulatory system........it's infact part of the nervous system. \n\nThe nervous system of an animal coordinates the activity of the muscles, monitors the organs, constructs and also stops input from the senses, and initiates actions as well. \n\nThe circulatory system consists of the heart, blood vessels, arteries, veins, capillaries, platelets and the plasma.  It's basically is an organ system that moves substances to and from cells.

The spinal cord. It forms as a sheet that rolls up into a tube, and from that, the brain develops.

if you dont breath for more then 4 minutes the brain cells start dieing - to hold on for longer would require a lot of practise. generally you pass out and the brain automatically starts the breathing process.\nonce brain cells die - there is no recovery - and you never know what part of the brain is dieing

without a pacemaker, such as an intermittent, the heart will continue to go into constant dysrythmia or atrial, ventricular, or sinus fibrillation. this makes it to where the hearts effectiveness(cardiac output) is decreased to nearly if not full asystole(without constriction) and blood will not flow through the body providing oxygen to all the tissues, including "the brain" and you will die due to ischemia- lack of oxygen. the pacemaker "paces" the heart keeping it under control like a kid on Ritalin

I think it's protein. Because most of the human organ need protein to be form. The human organ, including heart are consist of cells, and they need protein to regenerate, I think this also happens when they were formed in fetus period.

Brain is the portion of the vertebrate central nervous system that is enclosed within the cranium, continuous with the spinal cord, and composed of gray matter and white matter. It is the primary center for the regulation and control of bodily activities, receiving and interpreting sensory impulses, and transmitting information to the muscles and body organs. It is also the seat of consciousness, thought, memory, and emotion. \nA functionally similar portion of the invertebrate nervous system. \n\nIntellectual ability; mind: a dull brain; a quick brain. \n\nMind the capacity of thinking, reasoning, and acquiring and applying knowledge. Mind refers broadly to the capacities for thought, perception, memory, and decision: “No passion so effectually robs the mind of all its powers of acting and reasoning as fear” (Edmund Burke). Intellect stresses knowing, thinking, and understanding: “Opinion is ultimately determined by the feelings, and not by the intellect” (Herbert Spencer). Intelligence implies solving problems, learning from experience, and reasoning abstractly: “The world of the future will be an ever more demanding struggle against the limitations of our intelligence” (Norbert Wiener). Brain suggests strength of intellect: We racked our brains to find a solution. Wit stresses quickness of intelligence or facility of comprehension: “There is no such whetstone, to sharpen a good wit and encourage a will to learning, as is praise” (Roger Ascham). Reason, the capacity for logical, rational, and analytic thought, embraces comprehending, evaluating, and drawing conclusions: “Since I have had the full use of my reason, nobody has ever heard me laugh” (Earl of Chesterfield). The human consciousness that originates in the brain and is manifested especially in thought, perception, emotion, will, memory, and imagination. \nThe collective conscious and unconscious processes in a sentient organism that direct and influence mental and physical behavior. \nThe principle of intelligence; the spirit of consciousness regarded as an aspect of reality. \nThe faculty of thinking, reasoning, and applying knowledge
