Dictionary » D » Digestion




(1) (physiology) The catabolic process in the digestive tract where ingested food is converted into simpler, soluble and diffusible substances that can be assimilated by the body

(2) (microbiology) The process of decomposing organic matter through microbial activity

(3) (medicine) Suppuration


In physiology, digestion pertains to the mechanical and chemical processes to break up food into smaller or simpler constituent parts that can be absorbed or assimilated.

Different organisms utilize different ways to digest food. Some organisms employ external digestion whereas others use internal digestion. Many fungi, for instance, use external digestion in which food is digested from the outside through secreting enzymes that degrade food material and then absorbed through diffusion. With internal digestion, organisms digest their food in a closed system such as through the digestive tract, as in those of many animals.

amplification in no RT control

... reagents are 'good' I have tried cDNA at 10ng and 5ng and primer conc. at both 200uM and 400uM. I'm kind of out of ideas now...more/longer DNase digestion? Or does this sound more like an optimisation issue? Thanks in advance for your input.

Souther blot and restriction mapping

... constructing a restriction map from Southern Hybridisation data. I can construct restriction maps from fragment data obtained through endonuclease digestion and separation by standard gel electrophoresis, however, Southern Blot data only shows those fragments that a probe has hybridised to and ...

Re: drink water, orange juice or Cola before eating?

... agree that drinking while eating can adversely affect the digestive process. Additionally, drinking carbonated beverages brings other factors into digestion. When the carbon dioxide enters the stomach, the pyloric sphincter (which is closed while the first stages of digestion occur in the stomach) ...

... answers. It seems maybe they do all come from one fertilised egg, but maybe that's just every zooid WITHIN a given group of zooids, like the digestion ones for example. Though from reading, by now I'm pretty sure the whole entire thing comes from one egg. (if so, then how the four specialised ...
