what is a human body system? I just need the definition, nothing more, nothing less, something simple?

I'll give you a web site where you can find the answer nothing less nothing more.\n\nhttp://www.stcms.si.edu/hbs/hbs_student.htm

The basic levels of organisation are - from least complex to most complex:\nCell - the atomal unit in biology\nTissue - a collection of interconnected and similar cells with a similar function\nOrgan - A collection of discrete but distinct tissues which are involved in performing a basic function (eg a skeletal muscle is composed of blood, nerve and  contractile tissues)\nOrgan System - A collection of organs that regulate or control a common function.  (eg the nervous system).

????\nI don't understand your question...whatcha mean one organ? The human body has many organs...are you saying this person only has one organ left in their body? Sounds to me, their lucky to even be alive.

Our skin is the largest organ of our body. Skin serves several functions: it guards the underlying organs and muscles, it regulates our body temperature, it provides our sense of touch and it synthesizes vitamins D and B.\n\nThe skin includes parts like our hair and nails. In addition, there are several layers to skin, e.g., the epidermis and the dermis. Skin accounts for 15% of our body weight so you can see why it's called the largest organ in our body.\n\nThe above is basic information and you can already see how complex skin is. So there's lets to research and talk about when you're talking about skin.\n\nHope this helps.

The respiratory system is how you breath in and out. In fact, any organism that participates in gas exchange has a respiratory system. In humans and other mammals, the respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body.

Vascular refers to the transport of materials through a network.  Our vascular system transports blood.  Plants   that have a vascular system (similar to the veins and arteries we have) transport water through it.   Simple plants don't have a vascular system and rely on being small (~1 to 2 cm high) so that they don't have to transport water.

The endocrine system is the collection of organs and tissues that make hormones.  The hormones themselves control many things throughout your body, from development to emotional states to simple digestion.  As chemicals which circulate though your blood, they are considered to be 'fast' signals, though not as fast as nerve signals and the like.  Hormones are also never stored in your body... just made quickly as they're needed and used quickly.

The most amazing thing about the human body...\n\nReproduction? The heart? The brain? The digestive system? The circulatory system? Nah. None of these are the most amazing thing about our bodies, simply because these things can be done by other animals. The most amazing thing about the human body is the ability humans have to reason, to think creatively, and to act independent from a group. Basically, what sets us apart from animals is our ability to think through situations and come up with rational answers and solutions to problems.

You mean like a system? Digestive system is stomach, intestines, liver, etc. Immune system & others. Not 100% clear on what you want.

The system of veins and arteries that moves (circulates) the blood around in your body.

A system of anything is a set of things that work together. A computer hardware system would be: a processor unit, connected to a monitor (screen) or more, plus printers, storage devices (disks), modems, and so on. So, I could ask: Is the system up, which means is the computer hardware system working. A system may also mean a software (program) system, a program that runs on the hardware system. So, a word processor (like Word) is an application system (actually an application system is a bigger system, so maybe MS Office is a system) that runs on the hardware system. So, I could ask: Is the system up? which means is the software running.

No offense to the other people who answered, but you've gotten some unintelligent and outright dumb answers.  \n\nFirst, you have to define 'life'.  Merriam-Webster (see www.m-w.com) includes 20 definitions!  Here are the pertinent ones, with more comments below.  \n\n"1 a : the quality that distinguishes a vital and functional being from a dead body b : a principle or force that is considered to underlie the distinctive quality of animate beings -- compare VITALISM 1 c : an organismic state characterized by capacity for metabolism, growth, reaction to stimuli, and reproduction"\n\n"5 a : the period from birth to death "\n\n"8 : a vital or living being; specifically : PERSON <many lives were lost in the disaster>"\n\nDefinitions 1a and 8 define life one way, while 1c and 5 define life in different ways.  It is all in how one interprets them...\n\nMany biologists, including myself, define the beginning of life as the point in time when an organism is viable.  That means that an organism is able to survive in the external environment without nurturing from the parents.  A conservative estimate for the point of time when a fetus might be viable is at the end of the second trimester.  To err on the side of caution, we can even push this back a month; let us say at 5 months instead of 6.  We can push it back a month to account for future increases in technology.  Carl Sagan strongly agrees with this point of view and describes it much more eloquently than I could possibly explain it his book "Billions and Billions".  \n\nDefinition 5a spells out that life begins at birth and ends at death.  This is straightforward but I doubt few would 100% agree with it. \n\nDefinition 1c is at the seat of the controversy over when life begins.  If someone defines life as “the capacity for metabolism, growth, reaction to stimuli, and reproduction”, no one can make the philosophical or logical argument that life doesn’t begin at fertilization or conception.  At that point, one can only lay out their argument for when they feel life begins.  According to the National Institute of Health (NIH), about 50 percent of all fertilized human embryos are spontaneously aborted.  Figuratively, when an embryo is spontaneously aborted, it has reached the ‘end of its life’ (see other definitions of ‘life’), but it doesn’t mean the embryo was alive.  \n\nIn closing, the definition one ascribes to ‘life’ depends on their moral, social, and religious views.  Despite obvious differences in how people will define life, it is paramount to understand someone’s definition, and I hope this little answer helps just a little.

There is a definition used when considering something as .. human/noid. I can't remember it all but it's something like\n1. conscious of itself   \n as the number one definition. \nThey would be considered people.. just not "Human".. most likely they would be more advance than us and we would be the intellegent animals to them.

You are using the word organism incorrectly. the body is made up of billions of interconnected, interdependent cells. A single cell from the body cannot survive on its own once removed from the body. There are however single cell organisms that live within the human body but are not a part of it and are seen for the most part as hostile by the bodies immune system...while others such as those found in yogurt cultures are extremely beneficial to the human body but are still not a part of it.

The World Health Organization (WHO) has defined health as "a state of complete physical, mental, and social well-being and not merely the absence of disease."\n\nWhat language is that underneath your question?
