The human machine has three major sources of input energy: carbohydrates (bread, grains and simples sugars such as those in milk and fruit), protein (meat, legumes) and fats (too many kinds to name). When the body consumes one of these energy sources, the food molecules are broken down into smaller pieces using enzymes--doing so releases the stored energy in the food and provides small pieces from which to build more complex molecules. \n\nEach food source has a specific role to play in metabolism. Carbohydrates are the dietary source of an important sugar called glucose. In fact, carbohydrates, such as the starch in potatoes, are simply very long chains of connected glucose molecules. Glucose is so important because it is the only source of fuel for the brain, red blood cells and several other tissues. Your brain uses about 120 grams of glucose per day. Any carbohydrate consumed in excess of what is needed for running the body's basic metabolic processes is converted to glycogen or fat for long term storage.

Digestive System Organs\n\nEsophagus- A simple conduit between the mouth & stomach.\nStomach- Where the enzymatic digestion of proteins initiated and foods are reducted to liquid form.\nLiver- It's major role is to provide bile salts to the small intestine, which are critical for digestion & absorption of fats.\nPancreas- Important roles as both and endocrine & exocrine organ- provides a potent mixture of digestive ezymes to the small intestine which are critical for digestion of fats, carbs and protein.\nSmall Intestine- Where the final stages of chemical enzymatic digestion occur & where almost all nutrients are absorbed.\nLarge Intestine- Major differences among species in extent & importance - in all animals water is absorbed, bacterial fermentation takes place and feces are formed. In carnivores, that's about the extent of it, but in herbivores; like the horse, the large intestine is huge and of critical importance for utilization of cellulose.\n\nEXCRETORY ORGANS\n\nLUNGS- Diffuses carbon dioxide from the blood, into the lung tissue, and then leaves the body everytime we exhale.\nLIVER- The largest internal organ in our bodies. Its numerous functions make it part of the circulatory, digestive, and excretory systems. Some proteins & other nitrogenous compounds are broken down in the liver by a process called deamination. The liver produces bile, which is temporarily stored in the gall bladder before being released into the small intestine where it helps break down lipid molecules. The liver removes & breaks down old red blood cells. It is also responsible for maintaining normal levels of glucose in the blood. The liver is ALSO responsible for removing potentially hazardous chemicals from the blood. It "detoxifies" the blood.\nSKIN- Sweat comes out of pores in your skin. Sweat is a mixture of 3 metabolic wastes: water, salts, & urea. So as you sweat, your body accomplishes 2 things: sweating has a cooling effect on the body, and metabolic wastes are excreted.\nKIDNEYS- they filter the blood. The kidneys help filter the blood.\n\nRESPIRATORY \n\nNose & Nasal Cavity- airway, moistens & warms air, filters air, resonating chamber for speech, houses smell receptors.\n\nPharynx (throat)- connects nasal cavity to oral cavity & larynx & esophagus. Is a common path for air and food.\n\nLarynx (voice box)- Provides an open airway. Routes food to the esophagus & air to trachea.\n\nTrachea (windpipe)- Descends from larynx & divides into the 2 primary bronchi. Is mobile; stretches, recoils, moves side to side. \n\nLungs- are the collective arrangement of the respiratory zone.

LIPIDS:\nOne function for Lipids is that of Energy storage. Lipids contain a lot of calories in a small space. Since Lipids are generally insoluble in polar substances such as water, they are stored in special ways in you body's cells. Lipids can also function as structural components in the cell. Phospholipids are the major building blocks of cell membranes. Lipids are also used as hormones that play roles in regulating our Physiology (metabolism). \n\nCARBOHYDRATES:\nThe main function of carbohydrates is to provide energy, but they also play an important role in the structure and function of the body organs and nerve cells \n\nPROTEINS:\nProteins have many functions. They serve as enzymatic catalysts, are used as transport molecules (hemoglobin transports oxygen) and storage molecules (iron is stored in the liver as a complex with the protein ferritin); they are used in movement (proteins are the major component of muscles); they are needed for mechanical support (skin and bone contain collagen-a fibrous protein); they mediate cell responses (rhodopsin is a protein in the eye which is used for  vision); antibody proteins are needed for immune protection; control of growth and cell differentiation uses proteins (hormones).  These are just a few examples of the many, many functions of proteins.

Balance Your Body Chemistry.\n\nIf you've ever taken chemistry in high school you're familiar with this simple experiment to test the conductivity of salt. Two ends of an electrical wire are attached to a light bulb. The other ends are submerged in a glass of water. Because water alone is not conductive, the bulb does not light up. But when we add a little salt to the water the bulb starts to glow.\n\nIt's the same with our body. When we lack the natural elements in salt we suffer from a chronic energy deficit, or deficit of information. Salt is a core essential nutrient with exceptional abilities and qualities fundamental for keeping us alive.\n\nScience and medicine have tried to define the precise roles of salt in the healthy and diseased human organism. Blood, sweat, and tears all contain salt, and both the skin and the eyes are protected from infectious germs by the anti-bacterial effect of salt. When salt is added to a liquid, particles with opposite charges are formed: a positively charged sodium ion and a negatively charged chloride ion. This is the basis of osmosis which regulates fluid pressure within living cells and protects the body against excessive water loss (as in diarrhoea or on heavy sweating).  Sodium and chloride ions, as well as potassium ions, create a measurable difference in potential across cell membranes. This ensures that the fluid inside living cells remains separate from that outside. Thus, although the human body consists mainly of water, our "inner ocean" does not flow away or evaporate. Sodium ions create a high pressure of liquid in the kidneys and thus regulate their metabolic function. Water is extracted through the renal drainage system. The body thus loses a minimal amount of essential water. Out of 1500 litres of blood which pass daily through the kidneys, only about 1.5 litres of liquid leave the body as urine. \n\nSalt is "fuel" for nerves. Streams of positively and negatively charged ions send impulses to nerve fibres. A muscle cell will only contract if an impulse reaches it. Nerve impulses are partly propelled by co-ordinated changes in charged particles.

The kidneys serve two major functions: they keep the salt content of the blood constant, and they filter waste out of the bloodstream. So, the main components of urine are (salt) water and waste products. The major waste product from cells in the body is ammonia, and the major waste product from blood is a broken form of heme called bilirubin. In the liver, each of these is converted into a less hazardous form: ammonia is converted to urea, and bilirubin is degraded to urobilins. Salt, water, and urea are all colorless, but urobilins (which come from degraded pigments) are yellow. So, if you drink a lot, your urine will be more dilute and clearer, and if you get dehydrated, your urine will contain less water and be darker yellow.

Excretion is the process of eliminating waste products of metabolism and other materials that are of no use. It is an essential process in all forms of life. In one-celled organisms wastes are discharged through the surface of the cell. The higher plants eliminate gases through the stomata, or pores, on the leaf surface. They also have been shown (by British biologist Brian J. Ford) to translocate wastes into leaves which are then shed. In this fashion, the leaf, in addition to acting as an energy-trapping structure, is also a plant's organ of excretion.\n\nMulticellular animals have special excretory organs. In humans the main organs of excretion are the kidneys and accessory urinary organs, through which urine is eliminated (see urinary system), and the large intestines, from which solid wastes are expelled. The skin and lungs also have excretory functions: The skin eliminates water and salt in sweat, and the lungs expel water vapor and carbon dioxide." [1]\n\nIn mammals, for example, the two major excretory processes are the formation of urine in the kidneys and the formation of carbon dioxide (a human's most abundant metabolic waste) molecules as a result of respiration, which is then exhaled from the lungs.\n\nThe waste products are eliminated by urination and exhalation respectively. In urination, Hormone control over excretion occurs in the distal tubules of the kidneys as directed by the hypothalamus.\n\nPerspiration is another excretory process which removes salts and water, although the primary purpose is cooling.\n\nIn insects, a system involving Malpighian tubules is utilized to excrete metabolic waste. Metabolic waste diffuses or is actively transported into the tubule, which transports the wastes to the intestines. The metabolic waste is then released from the body along with fecal stuffs.\n\nMany people misuse the term excretion as a sort of euphemism for defecation, and use excrement for feces, but this is medically improper.\nhttp://en.wikipedia.org/wiki/Excretion\nhttp://en.wikipedia.org/wiki/Excretory_system

WindWalker's statement that oxygen is necessary for the synthesis of nutrients we need is a little misleading.  Oxygen is basically the end of the electron transport chain, and binds hydrogens that have passed though the ion gradient of the mitochondiral matrix to form water.\n\nHydrogen passes through this gradient in the mitochondrial matrix via passive, channel mediated transport.  The concentration of H+ on one side is high, and low on the other, since they get bound to Oxygen to form water.  Every time an H+ ion passes through, energy for ATP production is derived.

Cells are the basic building blocks of life. Their main goal is to maintain homeostasis, the way this is done is by using organic and inorganic molecules. Organic molecules are compounds containing carbons, whereas inorganic molecules are compounds that don't have carbon.  \n\nOne of the cells' main function is to make energy. The way it makes energy is via the Kreb Cycle, where it uses  organic molecules such as glucose, and breaks it down into energy ATP  another organic molecule. \n\nAnother function is Reproduction/Replication...cells use RNA (organic molecule) to make DNA (organic molecule).\n\nIf you look at cells on a larger scale, such as tissues...  note that there are four types of tissues: nervous tissues, connective tissue, muscle tissue, and  epidermal tissue.... if you look at the nervous tissue in order for a signal to be transmitted from the brain to the muscle,  neurons have to be able to send the message from the brain to the muscle using action potentials, which use inorganic molecules such as sodium and potassium, in the ion channels in a voltage sensitive gate.  Due to diffusion and osmosis, the ion gates open and close based on concentration levels of sodium and potassium and also based on the action potential. \n\nNote: that you question is very broad and requires not only the knowledge of basic biology but systemic physiology as well. If you want more answers or something you may email me.

The main mechanism of energy production in the body is through the formation and oxidation of adenosine triphosphate, ATP.  Cells convert carbohydrates (which we eat) into ATP, and then oxidize the molecules later to access the energy in their chemical bonds.
