describe water regulation in man.?

There are three fields of temperate solvents that tally the\n  degree of peoples water level.  One is the general physical\n  attention given to the intake, and use within the bodies action.\n  Generally athletes sweat the most though it is not in water\n   loss it is in belly over heating and steaming out liquids that\n   are similar to sweat.  Second the balance of water that is \n   generally required matters what you do, and this is tempo in\n   cohesive moving according to outside influence like the air,\n   temperature and that relation to sweat in work units that are\n   limited for the day.  Third there is outside influence to counter\n   effect  like cold, or heat, dry , or damp so the body does not\n   seek water to replace or dominate the blood flow and the many\n   minerals that men require ( or women ) to function cool and\n   strong activities.

Water is used in about all of the chemical processes in the body. Therefore it is a waste product in most of these reactions. The very act of breathing requires the use of water. No machine is so efficient as to have absolutely no loss in any of the variables involved in it's working. Some creatures are very efficient at retaining water but at a price to other bodily functions and even then they will eventually dehydrate and die without water.\nThis is really a pretty simple concept.

If you are talking about some one chronicly ill with any type of fluid build up in the body its called third spacing, the water has to go somewhere when the kidneys aren't functioning properly \n\nSource(s):\n\nrespiratory therapist

The relative amount of salts and water in our body must be regulated and kept steady.\nOur kidneys adjust the amount of salt and water in our body.\nToo much salt or not enough water makes us feel thirsty and we drink.\nToo much water for the amount of salt inside us and our kidneys dump the water into urine.\nThe most variable process affecting the salt/water balance (apart from eating and drinking) is sweating. If we lose a lot of water as we sweat a lot during hot weather then there is less water put into urine. When we don't sweat much the extra water is lost in urine.\n\nThe habit of eating salted crisps and peanuts developed from a marketing idea in pubs. Provide free crisp and peanuts on the bar and customers eat lots of salt. This makes us feel thirsty so we buy more drinks.

Excessive water intake is called psychogenic diabetes insipidis.  The only real problem is you will have to pee a whole lot, and you could make your blood hypotonic or even cause dumping syndrome in your intestines.

Hormone Control of Water and Salt \nWater reabsorption is controlled by the antidiuretic hormone (ADH) in negative feedback. ADH is released from the pituitary gland in the brain. Dropping levels of fluid in the blood signal the hypothalamus to cause the pituitary to release ADH into the blood. ADH acts to increase water absorption in the kidneys. This puts more water back in the blood, increasing the concentration of the urine. When too much fluid is present in the blood, sensors in the heart signal the hypothalamus to cause a reduction of the amounts of ADH in the blood. This increases the amount of water absorbed by the kidneys, producing large quantities of a more dilute urine.\n\nAldosterone, a hormone secreted by the kidneys, regulates the transfer of sodium from the nephron to the blood. When sodium levels in the blood fall, aldosterone is released into the blood, causing more sodium to pass from the nephron to the blood. This causes water to flow into the blood by osmosis. Renin is released into the blood to control aldosterone.

76% of human body is water. this figure is not same to every body do the climate that they live. The habits of drinking water also may show differ answer like the chiness people in general like to drink water a lot.\n\nFor example: people in Sahara may consist of less water compare to people in Alaska.\n\nClimate, alitude, temperature and others may affects the readings.

Balance you mean. Imbalance doesnot require regulation.\n\nThe process you refer to is urine formation. \n\nThe organ involved is the kidney (and its constituent nephrons).\n\nHormonal effects of aldosterone (and other mineralocorticoids of the adrenals), vasopressin, renin etc. also play a role. \n\nFollow the links below for more information.

I found this perspective posted by Jeffrey Utz, MD, Neuroscience, pediatrics, Allegheny University:\n\n"Different people have different percentages of their bodies made up of water. Babies have the most, being born at about 78%. By one year of age, that amound drops to about 65%. In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of thier bodies made of water. Fat men also have less water (as a percentage) than thin men.\n\nSo you can see three possible reasons for the discrepancies you have found:\n\n1) Babies and kids have more water (as a percantage) than adults.\n2) Women have less water than men (as a percentage).\n3) Fat people have less water than thin people (as a percentage).\n\nA forth reason is that different people measure per cent water a little differently, causing small differences in the answer."

What you describe is the process of osmosis. Osmosis is actually simple diffusion through a semipermeable membrane. The cell membrane is just such a selective permeable membrane. This allows for the movement of water, and controls what can enter and leave the cell. In fact osmosis is the only way water moves through the body. A good example is sweating, the sweat gland does not pump water the human body cannot do that. Instead it pumps salt and urea to the skin surface, and through the process of osmosis water will follow. Osmosis is going from a high concentration of water to a lower concentration of water (thru the membrane)until equib. is achieved.

There is a condition called water intoxication but you really have to drink a lot of water.  It basically dilutes the electrolytes in your body to a degree that it can't function properly and is a life threatening condition.  I think someone would have to force themselves to drink that kind of volume, though, since it would not be easy.
