  2. Absorption of water - Wikipedia

    en.wikipedia.org/wiki/Absorption_of_water

    Active absorption refers to the absorption of water by roots with the help of adenosine triphosphate, generated by the root respiration: as the root cells actively take part in the process, it is called active absorption. According to Jenner, active absorption takes place in low transpiring and well-watered plants, and 4% of total water ...

  3. 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.

  4. Human digestive system - Wikipedia

    en.wikipedia.org/wiki/Human_digestive_system

    Most of the digestion of food takes place in the small intestine which is the longest part of the GI tract. The largest part of the GI tract is the colon or large intestine. Water is absorbed here and the remaining waste matter is stored prior to defecation. [2] There are many specialised cells of the GI tract.

  5. Selective reabsorption - Wikipedia

    en.wikipedia.org/wiki/Selective_reabsorption

    Water can move freely through the wall of the PCT (it does not require a transporter protein). Nearly all the rest of the water is reabsorbed into the blood in the loop of Henle and the collecting duct system. However, as urea is a small molecule it can pass easily through the membrane of the PCT wall. As the concentration of urea in the ...

    en.wikipedia.org/wiki/Transcellular_transport

    In contrast, paracellular transport is the transfer of substances across an epithelium by passing through an intercellular space between the cells. It differs from transcellular transport, where the substances travel through the cell passing through both the apical membrane and basolateral membrane; Renal physiology. Transcellular transport is ...

  8. Absorption (pharmacology) - Wikipedia

    en.wikipedia.org/wiki/Absorption_(pharmacology)

    Absorption is a primary focus in drug development and medicinal chemistry, since a drug must be absorbed before any medicinal effects can take place. Moreover, the drug's pharmacokinetic profile can be easily and significantly changed by adjusting factors that affect absorption.

  9. Large intestine - Wikipedia

    en.wikipedia.org/wiki/Large_intestine

    It extracts water and salt from solid wastes before they are eliminated from the body and is the site in which the fermentation of unabsorbed material by the gut microbiota occurs. Unlike the small intestine, the colon does not play a major role in absorption of foods and nutrients. About 1.5 litres or 45 ounces of water arrives in the colon ...
