what are body chemicals and how do they affect human behaviors?
541977
That's a HUGE question you're asking, if I understand it correctly.  While the body is made up mostly of water, there's also an *enormous* number of biochemicals in the human body working in extremely complex ways, all of which affect human behavior, from whether your hungry to the color of your eyes to whether you're alive or dead.  Even biochemists don't know yet exactly what they all are and how they all work.\n\nA (very) partial list:\n\nhemoglobin\nserotonin\nbrain natriuretic peptide\nadenosine triphosphate\nacid phosphatase\nD-oxy-ribonucleic acid (DNA)\ntriglyceride\npyruvate dehydrogenase\nsuccinyl coenzyme-A synthetase\n1-aminocyclopropane-1-carboxylic acid\nbacteriorhodopsin\nbeta-hydroxy beta-methylbutyrate\nfarnesyl pyrophosphate, geranyl pyrophosphate and other acyclic sesquiterpines\n\n...to name a very few.

These drugs alter your body and brain chemistry...creating a Euphoric feeling and sensation...your body and brain cease to produce the proper levels of chemicals that are needed to perceive what is reality...Methadones create a feeling of "I don't care about anything or anyone."  Having no cares in the world while a pleasureable notion, NOT a realistic one...Life goes on while you are on Cloud 9 and before you know it...you are so deep in a pit of "not caring" that there is no one left to care about you...and eventually you will die...

You know hormones have great effects on your own behavior. Have you ever been very afraid, or angry? We are quite certain the human behavior is probabilistically influenced by heredity. The only argument left among scientist is the proportion of the heredity of behavior.

IThe body cannot process it and it causes toxicity

Depends on where you're talking about. There is no "overall" body chemistry influenced by all systems, but there are some spots that have a "normal" pH for that location, as:\n\nStomach: pH 2.0  (acid)\nBlood: pH 7.35-7.45 (slightly alkaline)\nUrine: pH average 6.0 (slightly acidic, can vary with diet)

The alcohol actually messes with your brain chemistry. It slows the reuptake of seratonin, for one, making you "happy" and "relaxed". It also affects the areas of the brain that control thought, reflexes, and all senses except hearing. Once your kidneys filter it out of your blood stream, you return to "normal".

Stress can directly and indirectly contribute to general or specific disorders of body and mind. Stress can have a major impact on the physical functioning of the human body. Such stress raises the level of adrenaline and corticosterone in the body, which in turn increases the heart rate, respiration, and blood pressure and puts more physical stress on bodily organs. Long-term stress can be a contributing factor in heart disease, high blood pressure, stroke and other illnesses.

Doctors use chemistry in many ways, but one of the main ways is in understanding how the body and physiology work. Chemical actions and activities are important processes in many aspects of our bodies and in other issues such as drugs (medicines) that will be used in our or on our bodies. Understanding chemistry is an important foundation to understanding these other areas.

Hormones and chemical changes. Anything chemical can mess around with your normal moods and physical/emotional feelings.

Cocaine produces a wide range of physiological effects in humans, including the stimulation of a plethora of emotional experiences. When people take cocaine, they become euphoric, highly active (locomotion, tremors, and tics), and more talkative than normal. They experience feelings of extreme power and alertness. This initial high is followed by bouts of severe anxiety, paranoia, and depression, which often lead to addiction. Those who become addicted to the drug often turn the habit into an obsession, so that they devote more, and more of their time and money to acquiring and using the drug. \n\nWithdrawal from cocaine can cause a drastic fall in the level of extracellular dopamine in the nucleus accumbens (Rosetti 1992). This decrease is thought to be caused by an increased secretion of dynorphin, one of the endogenous opioids.\n\nmore information in\nhttp://www.macalester.edu/psychology/whathap/UBNRP/Dopamine/cocaine.html\n\n \n(AP) Chronic cocaine use harms brain circuits that help produce the sense of pleasure, which may help explain why cocaine addicts have a higher rate of depression, a study suggests \nhttp://www.cbsnews.com/stories/2003/01/01/health/main534934.shtml

acid reacts with the organs present in our body.they will corrode,since they have the property of corrosion.hence acid is dangerous to human beings.

All sorts of factors affect the suitability of the human body fluids to sustain life; these include properties like temperature, salinity, and acidity, and the concentrations of nutrients such as glucose, various ions, oxygen, and wastes, such as carbon dioxide and urea. Since these properties affect the chemical reactions that keep bodies alive, there are built-in physiological mechanisms to maintain them at desirable levels.\n\nHowever, it should be noted that homeostasis is not the reason for these ongoing unconscious adjustments. Homeostasis should be thought of as a general characterization of many normal processes in concert, not their proximal cause per se. Moreover, there are numerous biological phenomena which do not conform to this model, such as anabolism.

A chemical imbalance of naturally occurring brain chemicals can affects a person in many different ways, and on many different levels.  It can make a person very complacent, like they just don't care about anything or anyone.  It can make them ultra sensitive sending them on an emotional roller coaster of extreme happiness to crying over even the littlest thing.  They may become angry more easily and possibly violent.  And depending on how severe the imbalance they sometimes hear and see things that are not there.  The best thing to do is see a psychiatrist, they are the only ones that can diagnose and treat the problem properly.

Neurological.  It's disalignment of chemicals in the brain. Certain drugs affect the dopamine balance in the brain.  The brain chemicals responding to these drugs proves it's neurological.

There are lots of neurochemicals, and the ones you're interested in are called neurotransmitters...\n\nMajor ones are: gamma amino bytyric acid; serotonin; norepinephrine; dopamine.  Also involved are countless polypeptides (often only a few aminoacids long, sometimes dozens) like melanin, the endorphins, the enkephalins, the endocannabinoids and others...\n\nWe're still unravelling the signalling systems and such of the brain, and the more we learn, the more complex it gets.\n\nThe big thing you have to realize is that the most recent data indicates that it is highly probably that the brain's chemistry is what is called (mathematically) deterministic chaos.  What that means is that any single small step is totally describable, and its immediate outcome is totally predictable, but when you expand to dozens or hundreds of steps, across large areas of involvement, it gets 'way out of hand, and the error of the estimate becomes larger than the estimate.  How environmental influences affect this is really tough to analyze, given the massive complexity and the incompleteness of our data.\n\nYour question, I fear, makes a whalloping lot more sense than my ANSWER, but, well, it's the best answer I've got...

There are some chemicals that enslave the body , no matter how strong the mind . The real strength comes in never beeing tempted to try drugs in the first place .
