### process:

Digestion
* Most digestion actually takes place there, rather than in the stomach
  - begins in mouths
  - creates methane
  - involves enzymes
  - is completed in the small intestine
  - occurs at degrees
* Most digestion occurs in animals
  - different animals
  - duodenums
  - intestines
  - organs
  - small intestines
  - stomachs
  - the upper portion of the small intestine, called the duodenum
  - produces bile
* Most digestion produces flammable gases
  - methane gases
  - natural gases
  - renewable natural gases
* Most digestion requires energy
  - takes place in the stomach
  - therefore occurs in the small and large intestines
* Most digestion uses digestive enzymes
* Recognizes the role of proper food storage and preparation in the prevention of illness.
* Some digestion has effects.
* Some digestion leads to calorie intake
  - diseases
  - lower calorie intake
  - neurological problems
  - lowers cholesterol
* Some digestion occurs in cavities
  - colons
  - compartments
  - esophagi
  - food vacuoles
  - requires fermentation
  - takes place in the stomach, much as in the stomach of man
* also stabilizes the sludge to reduce odors.
* begins externally and is completed intracellularly.
* begins in the mouth and ends in the large intestine
  - is completed at the anus
* begins in the mouth where feeds are chewed and wetted with saliva
  - salivary amylase starts the breakdown of carbohydrates
* begins in the mouth with the action of salivary amylase
  - salivary glands
* begins in the mouth, because there are certain bacteria in the mouth
  - well before food reaches the stomach
* begins in the stomach of an amphibian
  - with materials produced by gastric cells in the stomach lining
* begins with our saliva
* breaks down food into various nutrients
  - food down into small molecules
  - peptide bonds and affects the primary structure of the protein
  - the proteins down for use in the metabolism
* can help ducks stay warm
  - include nutritious molecules or potentially harmful molecules like alcohol
* can take a long time
  - hours or days
* ceases and peripheral blood vessels constrict.
* ceases, the circulation is reduced, and the immune and other defence systems slow or stop.
* certainly involves combustion.
* complex process controlled by several factors.
* complex, time-consuming and energy consuming process.
* consideration when reading a menu.
* consists of three processes.
* contributes to ability.
* destroys any hormonal activity.
* enzymes aid in food assimilation and chemical digestion.
* fails because the body has no energy left for production of enzymes and digestive juices.
* happens because of enzymes.
* includes both mechanical and chemical processes.
* involves actions
  - breaking organic compounds into simple soluble substances absorbable by tissues
* is also a chemical process, which varies with the kind of substance that is being eaten.
* is an example of catabolism
  - important Pitta activity
  - assisted by bacterial fermentation, like ruminants and other herbivores
  - both extra and intracellular
* is chemical change
  - complete when digestate is light in color
* is completed in the fourth stomach and nutrients are extracted in the small intestine
  - within food vacuoles of nutritive-muscular cells
  - considered a stressor so the body tries to resolve it relatively quickly
  - delayed by a decrease in gastrointestinal secretions
* is efficient and passage through the digestive system is quite rapid for a reptile
  - only within a certain range of body temperatures
  - entirely extracellular
  - essen- tially extracellular
  - essential in helping nutrients be absorbed by our intestinal cells
  - heat-mediated
  - immediately and clearly recognizable because of the discharge of excrements
  - improved, as is the immune system, and blood pressure can be lowered
  - incomplete if charring occurs upon contact of the two liquids
  - inhibited, breathing is shallow, the mouth is dry and the pupils dilate
  - internal and some solid food is taken in, which is uncharacteristic for arachnids
  - intracellular and is accomplished inside the food vacuole
  - intracellular, meaning that it occurs inside cells
  - known to be a process of oxidation
  - largely a matter of chemical changes in the food eaten
  - often the first processes disturbed in times of stress
  - primarily extracellular
  - rapid and faeces are expelled under pressure
  - slower in space due to a decrease in digestive tract movement
* is the A. chemical and mechanical breakdown of food into small molecules
  - break-up of the complex food chemicals into simple soluble absorbable subunits
* is the breakdown of food in the body
  - into smaller particles or individual nutrients
  - chemical and physical breakdown of food into compounds usable by the body
  - most energy consuming thing our bodies do
* is the process of breaking down food into nutrients
  - large food molecules into smaller ones
  - converting food to monomers
  - dissolving the food, making it more diffusible and available
  - splitting lactose back into glucose and galactose again
  - thus defective, intestinal putrification occurs, and body toxins accumulate
  - where 'eating right and good health' begins
* is, however, completed in the intestine.
* leads to elimination.
* necessary first step for all foods.
  - because of digestive juices which are secreted from the stomach
  - both in the stomach and in the glands themselves
  - by introducing a variety of micro-organisms into the effluent
* occurs in an autoclave
* occurs in the gastrointestinal tract, also known as the alimentary canal
  - intestine, with the caecum producing further digestive enzymes
  - inside food vacuole
  - outside the fungal body
  - subsidiary to absorption
  - that requires quite a bit of energy
* produces a great deal of heat and keeps the body warm during the evening rest in the tent
  - heat, but fat-supplemented feed generates less heat than fibrous feeds
* reduces the complex carbohydrates to simple sugars, which act as fuel in our body.
* relates to one's ability to digest the circumstances of one's life.
* releases the scolices, which mature in cattle and become adult tapeworms.
* requires actions
  - heat, which is focused energy
  - routing the blood supply to the digestive tract to pick up nutrients
  - some adaptation of the intestine like enlarged, sacculated parts of the colon
* serves the same function in animals.
* significantly reduces sludge quantity.
* slow process.
* slows affecting g absorption or nutrients from food
  - down when labour starts
  - down, breathing becomes shallower and blood pressure increases
* starts by breaking down the nutrients so they can absorbed and moved into the blood.
* starts in the mouth where chewing and saliva secretion occur
  - enzymes are released
  - with the partial break-down of starch by the enzyme ptyalin
  - when food is chewed in the mouth
  - with the teeth
* takes a large number of calories to complete.
* takes place in nearly a straight line down the earthworm's body
  - our bodies in the digestive system
* takes place in the intestine
  - stomach which occupies most of the mesosoma and part of the prosoma
  - stomach, with the aid of very strong digestive juices
  - with enzymes
  - without the aid of a stomach
  - places
* then occurs within a food vacuole.
* transforms into energy
  - heat energy
  - enzymatic hydrolysis to break bonds in macromolecules
  - up strength
* usually involves splitting of bonds between molecules, or between parts of molecules.
* works first by food entering the mouth and being masticated, or chewed.
+ Guppy: Ray-finned fish
  * Guppies have a tongue, teeth, a pharynx, gill slits, an esophagus, a stomach, intestines, and an anal opening. Digestion begins in the mouth. First, the food is mashed up into small pieces by the teeth. Then, the food travels down the pharynx. On either side of the pharynx, there are gill slits. Gill slits allow water to pass into the chambers, which helps break down the food even more. The food must pass through the esophagus in order to enter the stomach.
+ Ruminant, How rumination works, Details: Mammals
  * After this the digesta is moved to the true stomach, the abomasum. Digestion takes place here.
