Lab 1 - intro to excel and labscribe Flashcards
When should you choose an XY scattergraph?
When both sets of data are numerical in nature and on a continuous scale.
What is aerobic respiration?
A process in which oxygen is used in the biochemical reactions to generate ATP.
Trend in O2 consumption with increased activity:
Increased consumption as cells work to replenish their ATP stores.
Units for O2 consumption:
mLO2/g/h
Tell me about the iWorx214.
A peripheral hardware device that collects physiological information as electrical (analog) signals and converts them to digital signals. The digital information is sent via a USB connection to the computer for display and analysis by the LabScribe program.
What causes heart contractions?
Depolarization of the myocardial cells in the ventricles. Blood is forced into the major arteries of the circulatory system in a pulsatile manner.
What does a plethysmograph measure?
The pulses of blood moving in arteries
Homeostatic control of heart stuff:
Peripheral thermoreceptors tell the hypothalamus to signal for vasoconstriction or vasodilation.
What even happened in this lab? Experiment 1.
Measure pulse. Measure pulse with ice. Measure pulse without ice.
Save to where?
V. Definitely not R.
Units of pulse vs units on labscribe:
Pulse amplitude, milli/volts.
When should you choose a column graph?
When independent variables are not numerical. When you want to show multiple different data sets.
