  2. Fractionation - Wikipedia

    en.wikipedia.org/wiki/Fractionation

    The process of blood fractionation involves separation of blood into its main components. Blood fractionation refers generally to the process of separation using a centrifuge (centrifugation), after which three major blood components can be visualized: plasma, buffy coat and erythrocytes (blood cells). These separated components can be analyzed ...

  3. Bicarbonate buffer system - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate_buffer_system

    As calculated by the Henderson–Hasselbalch equation, in order to maintain a normal pH of 7.4 in the blood (whereby the pK a of carbonic acid is 6.1 at physiological temperature), a 20:1 ratio of bicarbonate to carbonic acid must constantly be maintained; this homeostasis is mainly mediated by pH sensors in the medulla oblongata of the brain ...

  4. Digestion - Wikipedia

    en.wikipedia.org/wiki/Digestion

    Digestion is the breakdown of large insoluble food compounds into small water-soluble components so that they can be absorbed into the blood plasma.In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

  5. Acid–base homeostasis - Wikipedia

    en.wikipedia.org/wiki/Acid–base_homeostasis

    The bicarbonate buffer, consisting of a mixture of carbonic acid (H 2 CO 3) and a bicarbonate (HCO − 3) salt in solution, is the most abundant buffer in the extracellular fluid, and it is also the buffer whose acid-to-base ratio can be changed very easily and rapidly. [15]

  6. Dialysis (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dialysis_(chemistry)

    Dialysis is the process used to change the matrix of molecules in a sample by differentiating molecules by the classification of size. [6] [7] It relies on diffusion, which is the random, thermal movement of molecules in solution (Brownian motion) that leads to the net movement of molecules from an area of higher concentration to a lower concentration until equilibrium is reached.

  7. High-performance liquid chromatography - Wikipedia

    en.wikipedia.org/wiki/High-performance_liquid...

    High-performance liquid chromatography (HPLC), formerly referred to as high-pressure liquid chromatography, is a technique in analytical chemistry used to separate, identify, and quantify specific components in mixtures. The mixtures can originate from food, chemicals, pharmaceuticals, [1] biological, environmental and agriculture, etc., which ...

  8. Aerobic digestion - Wikipedia

    en.wikipedia.org/wiki/Aerobic_digestion

    Aerobic digestion is a process in sewage treatment designed to reduce the volume of sewage sludge and make it suitable [1] for subsequent use. [2] More recently, technology has been developed that allows the treatment and reduction of other [3] organic waste, such as food, cardboard and horticultural waste.

  9. Filtration - Wikipedia

    en.wikipedia.org/wiki/Filtration

    Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated. Filtration, as a physical operation enables materials of different chemical compositions to be separated.
