  2. Management of dehydration - Wikipedia

    en.wikipedia.org/wiki/Management_of_dehydration

    This occurs when these over-concentrated solutions sit in the gut and draw water from the rest of the body, and the reduced fluids in the body's tissues then have a higher proportion of salt to fluid. Children with serum sodium greater 150 mmol/liter have thirst out of proportion to other signs of dehydration.

  3. Dehydration - Wikipedia

    en.wikipedia.org/wiki/Dehydration

    The symptoms of dehydration become increasingly severe with greater total body water loss. A body water loss of 1-2%, considered mild dehydration, is shown to impair cognitive performance. [9] While in people over age 50, the body's thirst sensation diminishes with age, a study found that there was no difference in fluid intake between young ...

  4. Fluid replacement - Wikipedia

    en.wikipedia.org/wiki/Fluid_replacement

    Fluid replacement or fluid resuscitation is the medical practice of replenishing bodily fluid lost through sweating, bleeding, fluid shifts or other pathologic processes. . Fluids can be replaced with oral rehydration therapy (drinking), intravenous therapy, rectally such as with a Murphy drip, or by hypodermoclysis, the direct injection of fluid into the subcutaneous tis

  5. Oral rehydration therapy - Wikipedia

    en.wikipedia.org/wiki/Oral_rehydration_therapy

    Without glucose, intestinal sodium is not absorbed. This is why oral rehydration salts include both sodium and glucose. For each cycle of the transport, hundreds of water molecules move into the epithelial cell to maintain osmotic equilibrium. The resultant absorption of sodium and water can achieve rehydration even while diarrhea continues. [40]

  6. Osmoregulation - Wikipedia

    en.wikipedia.org/wiki/Osmoregulation

    Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

  7. Fluid balance - Wikipedia

    en.wikipedia.org/wiki/Fluid_balance

    Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.

  8. Composition of the human body - Wikipedia

    en.wikipedia.org/wiki/Composition_of_the_human_body

    The adult human body averages ~53% water. [7] This varies substantially by age, sex, and adiposity. In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. [8]

  9. Digestion - Wikipedia

    en.wikipedia.org/wiki/Digestion

    Water and minerals are reabsorbed back into the blood in the colon (large intestine) where the pH is slightly acidic (about 5.6 ~ 6.9). Some vitamins, such as biotin and vitamin K (K 2 MK7) produced by bacteria in the colon are also absorbed into the blood in the colon. Absorption of water, simple sugar and alcohol also takes place in stomach.
