### process:

Absorption
* Most absorption begins in intestines
  - small intestines
  - causes chemical reaction
  - involves diffusion
* Some absorption also occurs in the lower intestine.
* Some absorption enhances immune functions
  - natural immune functions
* Some absorption lowers body temperature
* Some absorption occurs in duodenums
  - the stomach
  - promotes hair growth
* also occurs as sound propagates through the sea, and the energy is converted to heat.
* can also occur across the teguments, especially for small nutrient molecules
  - filter light
* can take place in two stages in the small intestine
  - over the entire visible spectrum
* comes from active transport.
* cooling produces a cooling effect by evaporating a refrigerant.
* creates effects
  - greenhouse effects
  - natural greenhouse effects
* critical parameter for climate studies and atmospheric corrections.
* decreases as the square of frequency.
* depends on the overall level of calcium in the food and the type of food being consumed
  - upon the presence of free unexcited ground-state atoms in the flame
* describes a reduction in light energy.
* increases significantly in the presence of acidic foods such as orange juice.
  - interaction
  - passive diffusion
* is affected by food or preparations containing divalent ions
  - reproductive condition and by ambient temperature
  - an active transport, requiring cellular energy
  - concerned with loss of gas within the commodity due to capilary forces
  - controlled by Vitamin D while excretion is controlled by parathyroid hormones
  - due to interactions between photons and electrons
  - enhanced by iron deficiency
* is enhanced by the act of chewing, which causes slight abrasions in the tissue
  - vast surface area made up of folds, villi, and microvilli
  - vitamin D, proteins, lactose, phosphorus, stomach acid and magnesium
  - in the presence of lipids
  - when the drug is taken with food
* is increased by taking it with fat and by microfining the drug particles
  - when the stomach's digestive juices are active
  - light that neither transmit or absorbs
  - measured by sweeping a sideband through a range of frequencies to locate a resonance
  - mostly by vegetation on land and by the oceans
  - natural processes
  - part of extinction
  - slow and variable but food increases the rate and extent of absorption
* is the direct conversion of sound energy into heat
  - key to supplements that can provide maximum benefit in the body
  - movement of a chemical into a plant, animal or soil
  - net change in occupied units
  - opposite of reflection
  - other reason for loss of energy
* is the passage of alcohol into the blood
  - digested nutrients through the gut wall
  - food monomers into the blood stream
* is the process in which radiant energy is retained by a substance
  - through which water flows from the distribution network into soils
  - transfer of nutrients into the bloodstream from the intestine
  - uptake of pesticides or other chemicals into the plant or animal
  - used for both spectroscopic and imaging applications
  - when a substance is chemically integrated into another
* means the interception of some of the earthshine by atmospheric molecules.
* measures the change in occupied space.
* occurs at an atomic or molecular level and wavelength specific process
  - directly into the systemic circulation as there is no first pass metabolism
  - in the liver, pancreas and cecum
  - through the mucous membranes that line the mouth cavity
  - when energy from the radiative source is absorbed by the material
* often plays an important part in the repairs of injuries.
* process that redirects the beam energy.
* surface area dependent phenomenon.
* takes place primarily in the duodenum where the intestinal environment is still acid
  - through the plants' roots structures, stems and bodies
  - place, and tumours appear in each axilla
