  58. homeostasis
    the condition of equilibrium in the body's internal environment due to the constant interaction of the body's many regulatory processes
  59. feedback system
    also called feedback loop; a cycle of events in which the status of a body condition is monitored, evaluated, changed, remonitored, reevaluated, and so on.
  60. components of homeostatic feedback lope
    • receptor: monitors controlled condition, sends input to control center
    • control center: receives input and provides output
    • effectors: bring about a change in controlled condition
  61. negative feedback loop
    • reverses a change in a controlled condition
    • actions stops automatically when setpoint is reached
    • regulate conditions that remain fairly stable over long periods

    • Signs are what we can see: swelling, rashes, pus, fever
    • Symptoms are what the patient tells us: nausea, pain, headache...
  64. disease
    term for an illness characterized by a recognizable set of signs and symptoms which usually has a cure
  65. Syndrome
    • a set of signs/symptoms that often occur together
    • we usually don't understand the relationship btwn the s/s & disorder
    • no cure
  66. internal sources of disease
    occurs because of an imbalance of homeostasis from some sort of internal or genetically programmed abnormality. Ex: aging and gene mutations
  67. Auto-immune diseases
    something goes wrong with the homeostatic loop, part of body becomes altered, immune system recognizes alteration as "non-self" and attacks when it shouldn't
  68. external sources of disease
    • disruptions in homeostasis by outside agents
    • ex: infectious disease
  69. Modes of disease transmition
    • Contact transmission: direct(touching), indirect (shared objects), or droplet

    • airborne transmission: only applies to pathogens, which stay alive in droplets or dust traveling
  70. fomites
    • shared objects
    • Ex: doorhandles, desks, etc
  71. vector transmission
    if a disease that is transmitted by a "third party" (by an insect bite, bat, etc), then the animal is called a vector

    people can be vectors, if they transmit the disease but do not appear to be sick, they are called carriers
