### communication devices:

Fax machine
* Most fax machines use thermal paper, which turns black where heat contacts it.
* are communication devices
  - electronic devices
* are located in offices
* are the curse of mankind
  - least controllable technology when one transmits patient information
* can transmit anything already on paper.
* handle the delay and jitter of packet networks.
* have a special language for communicating with each other
  - calendar functions
* provide a new form of fast communication, but also require energy and paper.
* store incoming and outgoing pages in memory.
* use the same devices to communicate with one another.
* waste ink.

Assertive communication
* enhances self-esteem and relationships.
* expresses ideas and feelings about condoms.
* involves verbal and nonverbal messages.
* is less stress-producing than passive or aggressive communication.
* valuable skill to have when refusing offers or behaviors.

Asynchronous communication
* can involve group learning.
* changes the dynamics of work and how people contribute.
* emphasizes individual learning.
* is the prevailing standard in the personal computer industry
  - used for several reasons
* means that communication is delayed.
* protocol for coordinating serial data transfers.

Business communication
* is communicating
  - essential to the health of any organization
* key aspect of what it takes to succeed.

### communication:

Circulation
* Compare the anatomy and efficiency of open and closed circulatory systems.
* There are two types of channels that carry blood around our bodies.
* begins early in fetal life
  - with oxygenated blood entering the fetus through the umbilical vein
* carries heat to the cold surfaces.
* causes nutrients and sediments to be mixed and resuspended.
* explain how air and storm systems travel over the Earth's surface.
* helps increase oxygen levels in the water.
* improves in all the arteries of the body, both large and small.
* improves, internal organs function better, and muscles and joints become more flexible.
* is academic journals
  - an escalation of energy
  - as important to financial health as it is to physical, mental, and emotional health
  - counts
  - deemed to have been established once fluid reaches the surface
  - dissemination
  - spread
  - the number of copies sold by a magazine in one issue
  - vital, the feet are one of the first places to get cold
* occurs in the hotter, lower layers of the mantle.
* provides a crucial missing link connecting inflammation to heart attack.
* refers to lending and borrowing library materials.
* releases nutrients and renews hypolimnetic oxygen.
* then serves to bring newly oxygenated blood to the tissues of the body.

### communication | circulation:

Blood circulation
* becomes decreased so it has to be relieved immediately through surgery.
* ceases partially or completely.
* delivers oxygen and removes carbon dioxide from all of the tissues of the body.
* drops as heart begins to slow down.
* increases, but digestion slows down or even stops.
* is enhanced as the capillaries open, for example
  - increased by the dilation of capillaries
  - regulated in the lower abdomen
  - very important to deliver nutrients especially oxygen to the organs

Collateral circulation
* connects the proximal and the distal aspects of the vessels over time.
* is divided into anterior and posterior systems.

Impaired circulation
* can mean slow or poor healing when injuries do occur.
* is certainly a large part of the problem with diabetic healing.
