  2. Body water - Wikipedia

    en.wikipedia.org/wiki/Body_water

    The figure for water fraction by weight in this sample was found to be 58 ±8% water for males and 48 ±6% for females. [4] The body water constitutes as much as 75% of the body weight of a newborn infant, whereas some obese people are as little as 45% water by weight. [5] This is due to how fat tissue does not retain water as well as lean tissue.

  3. Swim bladder - Wikipedia

    en.wikipedia.org/wiki/Swim_bladder

    The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ in bony fish (but not cartilaginous fish [1]) that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift via swimming, which expends more energy. [2]

  4. Fish physiology - Wikipedia

    en.wikipedia.org/wiki/Fish_physiology

    The body of a fish is denser than water, so fish must compensate for the difference or they will sink. Many bony fishes have an internal organ called a swim bladder, or gas bladder, that adjusts their buoyancy through manipulation of gases. In this way, fish can stay at the current water depth, or ascend or descend without having to waste ...

  5. Water activity - Wikipedia

    en.wikipedia.org/wiki/Water_activity

    Water activity values can also help limit moisture migration within a food product made with different ingredients. If raisins of a higher water activity are packaged with bran flakes of a lower water activity, the water from the raisins migrates to the bran flakes over time, making the raisins hard and the bran flakes soggy.

  6. Hygroscopy - Wikipedia

    en.wikipedia.org/wiki/Hygroscopy

    For the hilum to close, this moisture needs to exceed some minimum level (14–25% for these species). [19] While the hilar valve is open (i.e., low outer humidity) if the humidity suddenly increases, the moisture tension reaches that protective threshold and the hilum closes, preventing moisture (liquid water) from entering.

  7. Moisture sorption isotherm - Wikipedia

    en.wikipedia.org/wiki/Moisture_sorption_isotherm

    Moisture sorption isotherm. The relationship between water content and equilibrium relative humidity of a material can be displayed graphically by a curve, the so-called moisture sorption isotherm. For each humidity value, a sorption isotherm indicates the corresponding water content value at a given temperature. If the composition or quality ...

  8. Human physiology of underwater diving - Wikipedia

    en.wikipedia.org/wiki/Human_physiology_of...

    The human physiology is evolved to suit atmospheric pressure conditions near sea level. Atmospheric gases at significantly greater pressures can have toxic effects which vary with the gas and its partial pressure, and the toxic effects of contaminants of the breathing gas are a function of their concentration, which is proportional to partial ...

  9. Water column - Wikipedia

    en.wikipedia.org/wiki/Water_column

    The (oceanic) water column is a concept used in oceanography to describe the physical (temperature, salinity, light penetration) and chemical (pH, dissolved oxygen, nutrient salts) characteristics of seawater at different depths for a defined geographical point.
