### process | reaction | reflex:

Blink
* are a shutting down of one's attention span long enough to miss pieces of the whole picture
  - reflexs
* arise from relatively simple neural circuits that control an uncomplicated mechanical system.
* occur most frequently at the end of an utterance.

### process | reaction | reflex:

Burping
* allows excess air, swallowed during sucking, to escape.
* helps prevent spitting up and belly aches.
* is an ejection
  - caused by air being trapped in the stomach
  - necessary to remove swallowed air from the baby s stomach
* method of expelling excess air from the fish's swim bladder.
* natural human phenomenon, but it's also possible for a bottle to burp.
* physical nature of people to expel gas from the stomach through the mouth.
+ Belching: Digestive system
  * Belching' is the act of making a burp. It is letting air out of the stomach  through the mouth. Burping is caused by air being trapped in the stomach.

Electrical shock
* Use nonmetal ladders around electricity.
* can cause personnel injury or death.
* can occur when a rat chews through a power cord
  - with metal or wet wooden ladders
* happen in welding when the person becomes a better ground than the ground cable.
* major electrical hazard.
* potential hazard aboard ship.

Fart
* are motivated by the goal of attention
  - crude
  - reflexs
* end with blushs
  - smell
* have less atmospheric gas content and more bacterial gas content than burps.
* start with blushs
  - moves
* tend to burn with a blue or yellow flame.

Goosebump
* actually serve a purpose in animals.
* caused by the contraction of the hair muscles can add to the effect.
* result from tiny muscles in the skin.

### process | reaction | reflex:

Hiccup
* are a nervous spasm of the muscles controlling the diaphragm
  - result of spasms of the diaphragm
  - universal part of the human condition
  - basically an involuntary inspiratory spasm of the diaphragm
* are due to periodic spasms of the flat diaphragm muscle, which controls respiration
  - stomach spasms
  - involuntary actions caused by the combined action of the diaphragm and the epiglottis
  - myoclonuses
  - normal during infancy
  - often rhythmic
  - symptoms
* can also be due to fast chewing of food
  - the result of overeating, stress, or minor stomach disorders
  - be quite common in infants and are noted by mothers before their babies are born
* is in the process of a recovery.
* result from repeated, involuntary spasmodic contractions of the diaphragm.

Mydriasis
* are dilation
* can be severe enough to block eyetracking
  - increase intraocular pressure by partially closing the iridocorneal angle
* is dilatation
* occurs naturally in youth, myopes, light colored irises and in anxiety.

Pupillary reflex
* are intact, but there is no menace response.
* is tested in a darkened room.

Reflex incontinence
* is the loss of bladder control due to impaired nerve function.
* occurs in persons with spinal cord damage.

Sneeze
* are healthy, and can help to remove germs, allergens, or dust from the nose
  - illnesses
* can be single or multiple.
* occur in rapid, multiple sequence.

Yawn
* are exhalation
  - motivated by the goal of tireds
* become contagious to people between the first and second years of life.
* seem to occur most often soon after waking and about an about before bedtime.

Reversible reaction
* have analogous mechanical examples.
* tend to approach an equilibrium.

Saponification
* are chemical reaction.
* cleaves the two esters bonds and frees monoalkyl glycerols.
* is reaction
* is the conversion of an oil and alkali into natural soap and glycerin
  - reaction between a fat and a base that produces soap
  - term applied to the hydrolysis of fats using a strong alkali like lye
  - what happens when a fatty acid meets an alkali
* occurs in the presence of a base to produce the carboxylate salt and alcohol.
* remains the basic chemistry.
