midterm Flashcards
insulin
takes up blood glucose from blood
lowers bld glucose
glucagon
when their is low blood glucose levels the pancreas releases it to bring levels back to normal
hyperglycemia
high blood glucose
hypoglycemia
low blood glucose
direct calorimetry
measures energy output by measuring heat ..exact measurement
indirect calorimetry
estimates energy output using respiratory gases
respiratory exchange rate
exchange ratio between oxygen intake and co2 output
basal metabolic rate
rate expidenture at rest
VO2 drift
increase in oxygen taken in during exercise
excess post oxygen consumption
the amount of oxygen the body takes in after exercise to recover
myelin sheath
fatty coverings around axon to help nerve impulse travel faster
resting membrane potential
-70 milli difference of electrical change
graded potential
change in resting membrane potential (at a certain level the channels open)
down regulation
receptor becomes desensitized
up regulation
increased sensitivity to hormone
