In biology, the tonicity of a solution usually refers to its solute concentration relative to that of another solution on the opposite side of a cell membrane; a solution outside of a cell is called hypertonic if it has a greater concentration of solutes than the cytosol inside the cell. When a cell is immersed in a hypertonic solution, osmotic ...
Hypertonic sport drinks contain a higher concentration of salt and sugar than the human body. Hypotonic sport drinks contain a lower concentration of salt and sugar than the human body. Most sports drinks are approximately isotonic, having between 4 and 5 heaped teaspoons of sugar per eight ounce (13 and 19 grams per 250ml) serving. [3]
Hypoosmolar hyponatremia is a condition where hyponatremia is associated with a low plasma osmolality. [1] The term "hypotonic hyponatremia" is also sometimes used.[2]When the plasma osmolarity is low, the extracellular fluid volume status may be in one of three states: low volume, normal volume, or high volume.
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.
It can be altered by behavior. Drinking large amounts of alcohol will reduce the biological half-life of water in the body. [8] [9] This has been used to decontaminate patients who are internally contaminated with tritiated water. The basis of this decontamination method is to increase the rate at which the water in the body is replaced with ...
It involves drinking water with modest amounts of sugar and salts, specifically sodium and potassium. [1] Oral rehydration therapy can also be given by a nasogastric tube . [ 1 ] Therapy can include the use of zinc supplements to reduce the duration of diarrhea in infants and children under the age of 5. [ 1 ]
In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is usually slightly lower in women (52–55%). [2] [3] The exact percentage of fluid relative to body weight is inversely proportional to the percentage of body fat. A lean 70 kg (150 lb) man, for example, has about 42 (42–47) liters of water ...
There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys. There exist several classes of diuretic, and each works in a distinct way. Alternatively, an antidiuretic, such as vasopressin (antidiuretic hormone), is an agent or drug which reduces the excretion of water in urine.
