### swelling:

Bloat
* can be a problem on wheat pasture.
* causes bloat.
* is also a risk at night when the days have been very hot
  - commonest in hand fed or older animals
  - more common among older dogs
  - of little concern, especially in grassy alfalfa, during a drought
  - often a problem for animals on pastures that contain a large proportion of white clover
  - responsible for substantial losses to the meat and dairy industries
  - when dry food is in the stomach and lots of water is ingested
* occurs in deep-chested breeds such as basset hounds
  - through the formation of foam in the cows' rumen
* occurs when gases fill the stomach like an inflating balloon
  - rumen gas production exceeds the rate of gas elimination
  - too much gas is produced in the rumen
* often problem for animals on pastured alfalfa.

### swelling | bloat:

Frothy bloat
* can be a major cause of death in stocker calves grazing wheat pasture.
* is more common in cattle eating legumes or lush grass than in feedlot cattle.

Hematoma
* is seen in the renal hilum.
* refers to a solid, homogeneously hyperdense image.

### swelling | hematoma:

Subdural hematoma
* Some subdural hematomas are small and can resolve on their own.
* can occur in people of all ages.
* is an unsual presentation for aneurysms.
* occur between the dura and arachnoid.
* occurs in people of all ages.
* raise the intracranial pressure and compress the brain.

### swelling | lymphedema:

Hereditary lymphedema
* arises spontaneously in individuals who have the genetic mutation.
* can affect one or all limbs and sometimes other parts of the body.

Primary lymphedema
* is caused by congenital malformations of the lymphatic system
  - more prevalent in females than males
* is the result of an imperfectly developed the lymphatic system
  - lymphatic dysphasia
  - when lymphatic vessels are missing or impaired
* occurs when the lymphatic system is underdeveloped from birth.
* occurs without an obvious cause
  - any obvious cause
  - obvious cause and can present at different stages
* seems to be inherited in several different ways.

Secondary lymphedema
* can develop immediately post-operatively, or weeks, months, even years later
  - postoperatively, or years later
* develops as the result of damage to the lymphatic system.
* is far more common than primary
  - often a result of infection, especially dermatophytosis in the foot

### swifter killer:

Synovial sarcoma
* are high-grade tumors, which are often associated with a poor prognosis.
* swifter killer.
* tends to recur locally and to involve regional lymph nodes.

Switch
* Convert mechanical motion to electrical motion.
* allow network designers to build large networks that function well
  - the control of multiple computers with only one keyboard, monitor and mouse
* are a fundamental part of most networks
  - an important part of electronics as they change the state of the circuit
  - capable of store information
  - codes placed behind the name of an executable file, and sometimes called parameters
  - control devices
  - couplers
  - devices used for the operation of an adapted electrical or battery operated unit
  - electrical components
  - electronic devices
  - hairpieces
  - located in television
  - networking hardware
  - part of electrical circuits
  - portals
  - railroad tracks
  - the brains of a network
  - very simple devices which can be used flexibly with a variety of children and adults
* can act on individuals, cohorts, or populations.
* is control

### switch:

Dimmer switch
* create ambience and help extend the life of the bulbs.
* expand the lighting range of a single fixture.

Light switch
* are located in rooms
  - such devices
  - switchs
* causes the lights to go on and off.
* have a lever which moves up and down.

Network switch
* are crucial elements in the provision of high speed networks.
* make the connection between one phone and another.
