  • 1
    - the heat is a form (type) of energy
  • 2
    - the heat is measured in J/K
  • 3
    - the heat is conducted through vacuum
  • 4
    - the heat is distributed within the body mainly by a conduction
  • 5
    - the heat leaves the body mainly by a conduction
  • 6
    - a cooling of the body (heat expenditure) can be provided by evaporation
  • 7
    - a spontaneous heat „flow“ is determined by the temperature gradient
  • 8
    - the body temperature is controlled by the central nervous system (CNS – the brain and the spinal cord)
  • 9
    - the high temperature can be detected also by nociceptors
  • 10
    - the body temperature is within the entire body constant
  • 11
    - the body temperature is within the entire body identical
  • 12
    - the body temperature depends exclusively on the amount of produced heat
  • 13
    - the body temperature depends exclusively on the amount of expelled heat
  • 14
    - the internal body temperature of human is well balanced
  • 15
    - an internal body temperature of human is usualy measured in axila, under the tongue (sublingual), within the rectum (rectal), and in an external auditory canal
  • 16
    - the temperatures in an axila and the mouth are equal
  • 17
    - the heat can be transported from a cooler body (object) to the warmer body (object)
  • 18
    - the thermoregulation controls the heat expenditure by redistribution of the blood
  • 19
    - the thermoregulation controls the body temperature also by an alteration of metabolic
    activity of the body
  • 20
    - the thermoregulation center represent the neurons of pituitary gland (hypophysis)
  • 21
    - the temperature difference is proportional to (added or taken) heat and inversely proportional to the thermal capacity
  • 22
    - the cooling power depends on the time of the organism being exposed to the atmosphere
  • 23
    - the cooling power is defined as heat loss from 1 m2 of the body surface that is exposed to the atmosphere
  • 24
    - a heat loss from the body depends on the temperature, the flow (e.g. airflow) and properties of surroundings (e.g. air humidity), and on the internal body temperature
  • 25
    - the thermoregulatory center integrates mainly stimuli from thermoreceptors and modifies the body activities in order to reach the internal body temperature desired by that center
  • 26
    - a maximal medical thermometer should be introduced for 2 min in the spot of taking the temperature and we have to read it immediately
  • 27
    - a fast measuring medical thermometer takes an actual temperature of a body place where it is introduced
