dicuss the normal physiologic mechanisms which regulates fluid and elecrolyte imbalance?

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.

Minerals (eg - sodium, potassium, magnesium, calcium) that regulate bodily functions. Small amounts are lost in sweat and need to be replaced through the use of energy drinks like Cytomax.\nIf you have been vomiting a lot you will lose a lot of your electrolytes. Sometimes in hospitals, you see people on Potassium 'drips' which put Potassium and other electrolytes straight into their bloodstream...

The hydrostatic pressure is generated by the pumping force of the heart. It pushes water out of the capillaries.\n\nThe water potential is created due to the inability of large solutes to pass through the capillary walls. This buildup of solutes induces osmosis. The water passes from a high concentration (of water) to a low concentration in an attempt to reach an equilibrium. This draws water back into the vessels. Because the blood in the capillaries is constantly flowing, equilibrium is never reached.\n\nThe balance between the two forces is different at different points in the capillaries. At the arterial end of the vessel, the hydrostatic pressure is greater than the water potential, so the net movement (see net flux) favors water and other solutes being passed into the tissue fluid. At the venous end, the water potential is greater, so the net movement favours substances being passed back into the capillary. This difference is created by the direction of the flow of blood, and the imbalance in solutes created by the net movement of water favoring the tissue fluid

Like the refractive index of urine (specific gravity) it depends on the concentration of the dissolved solutes. Other than using it as a baseline in the assays mentioned above, I can think of little purpose in performing it. It is non-specific, and even a reading in the 'normal' range would not preclude an electrolyte imbalance.

Tuesday nailed it. The saline you receive in an IV form is actually 0.9% saline it is a Isotonic solution.  It prevents the red blood cells from absorbing too much water and bursting, which would happen if you had an IV of plain water(hypo-tonic), and too much salt (Hyper-tonic)causes the cells to shrivel up causing water depletion. Now you can drink normal saline in fact the same amount of salt is found in most sports drinks.  Water can be consumed without your bodies cells absorbing too much due to what is called a sodium/chloride shift. It is also kept in balance by the kidneys.

Excretory systems regulate the chemical composition of body fluids.\n\nhttp://www.fi.edu/biosci/systems/excretion.html

Humidity affects indirectly, probably as related to sweating to rid of fluid.  But your kidneys are the main fluid eliminators, usually through a salt exchange. You need to know what the salt-ie sodium and potassium levels are, as well as your protein in your blood. Your hormones can be involved, as well as circulation of your blood and lymphatics. Blood pressure could be involved.Support stockings may help if everything else checks out OK.

Homeostasis \nHomeostasis is the physiological process by which the internal systems of the body (e.g. blood pressure, body temperature, acid-base balance) are maintained at equilibrium despite variations in the external conditions. \nThe body can maintain the fluid levels using the kidneys, these organs filter out harmful chemicals and excess liquid into the bladder from which the urine is then expelled.  Body temperature is regulated somewhat by the skin, example, if you are hot you begin to sweat and this helps to cool the body, if you are cold you shiver this helps to raise, the body temperature.

OPPS SORRY, I sent incomplete. Believe it or not, it is generally described as thus: The body wants to have 2/3 of the water inside the cells \n(intracellular fluid) and 1/3 of the water between the cells (extracellular) however a Teacher is probably looking for the technical name of: interstitial fluid

on drinking lot of water the osmotic pressure of blood falls and excess water is then absorbed by the nephron of the kidney and excreated out to maintain the osmocity of blood

Your concern is appropriate.  We are about 60% water by weight at birth but only 40% around age 80 so we all 'dehydrate' a bit.  Diuretics are a misnomer as they cause shifts in sodium and water in the body and they only cause water loss if there was extra water to begin with.  The need for water is in most cases constant with or without a 'diuretic' at about 1500 ml / meters squared of body surface area.  In theory you 'old' Dad is being followed by a physician so you should seek their advice.

Blood osmolarity is referring to ECF osmolarity - they equilibrate with each other and are thus nearly identical. High osmolarity is sensed by central osmoreceptors, which prompt ADH secretion. The blood volume is a second separate signal to secrete ADH; these receptors are in the peripheral vasculature.

be sure to let your MD know.  Could be dependent edema from the increased fluid loads given during the post op time, but could be signs of worse problems, such as a deep vein thrombosis- this could be lethal.  Also you might have CHF congestive heart failure, once again talk with your MD.  After that is done, you should be on a cardio rehab program that teaches proper eating, exercise and medication regiment.

because you have no way of expelling the excess amount of fluid but the next dialysis. and until then fluid will accumulate in your internal environment, raising your blood pressure causing edema to accumulate around your lungs. and causing many other troubles

not "drunk" but you can overhydrate yourself.\n\nWhen too much water enters the body's cells, the tissues swell with the excess fluid. Your cells maintain a specific concentration gradient, so excess water outside the cells (the serum) draws sodium from within the cells out into the serum in an attempt to re-establish the necessary concentration. As more water accumulates, the serum sodium concentration drops -- a condition known as hyponatremia. The other way cells try to regain the electrolyte balance is for water outside the cells to rush into the cells via osmosis. The movement of water across a semipermeable membrane from higher to lower concentration is called osmosis. Although electrolytes are more concentrated inside the cells than outside, the water outside the cells is 'more concentrated' or 'less dilute' since it contains fewer electrolytes. Both electrolytes and water move across the cell membrane in an effort to balance concentration. Theoretically, cells could swell to the point of bursting.

Drink lots of water.  By the way, salt is a natural expectorant as well as a natural antihistamine. Histamine is the body's response to dehydration since the role of histamine is to act as the master conductor of water management during dehydration.
