Exam 3: Objectives 70-74 Flashcards
what does acidity of a solution refer to?
free hydrogen ion concentration
what is the renal compensation for metabolic acidosis?
save HCO3- and eliminate H+
Increased adrenal secretion of epinephrine and activity of adipose tissue; Brown adipose tissue in infants
non-shivering thermogenesis
The process by which the surfaces of objects constantly emit heat in the form of electromagnetic waves
radiation
The loss or gain of heat by transfer of thermal energy during collisions between adjacent molecules.
conduction
which thermoreceptors have the greatest influence on body temperature?
peripheral
which method of heat transfer involves direct contact?
conduction
how do you calculate BMI?
weight (kg) divided by height squared (m)
what is the only form of backup for respiratory alkalosis?
renal compensation
what metabolic condition does diarrhea cause?
acidosis
what is the most immediate buffering system in the body?
intra/extracelluluar blood buffers
Water vaporizes from the skin and membranes lining the respiratory tract; the heat required to drive the process is conducted from the surface thereby cooling it
evaporation
how do the kidneys primarily change H+ ion concentration in the body?
altering plasma bicarbonate concentration
what is the renal compensation for respiratory alkalosis?
make less HCO3- and save H+
what is the main way we regulate body temperature?
radiation
what is the respiratory compensation for metabolic alkalosis?
decreased RR
Oscillating rhythmical muscle contractions and relaxations at a rapid rate; All energy liberated as heat not work
shivering thermogenesis
The process whereby conductive heat loss or gain is aided by movement of air or water next to the body
convection
what kind of respiration is associated with respiratory alkalosis?
hyperventilation
what is the respiratory compensation for metabolic acidosis?
increased RR
decreased respiration causes retention of CO2, which does what to the equation?
shifts right
what does high arterial H+ concentration do to ventilation?
stimulates ventilation
where is the regulatory control center for temperature?
hypothalamus and anterior pituitary gland
what metabolic condition does vomiting cause?
alkalosis
slower breathing does what to CO2 levels?
increases them
how are H+ or HCO3- levels affected in metabolic acidosis?
gain of H+ or loss of HCO3-
increased respiration causes loss of CO2, which does what to the equation?
shifts left
