Explanation should include
• physiological signals
o blood pressure
o blood flow
o respiration
o activity levels
• biopotentials
o electroencephalogram (EEG)
o electromyography (EMG)
o electrocardiogram (EKG)
• biochemical signals
o glucose level
o oxygen saturation.
Process/Skill Questions:
• How are biosignals generated?
• How are different biosignals related to underlying health and disease?
• How could the glucose level in a patient be influenced?
• Why might blood pressure increase or decrease?
• What variables might affect the rate and volume of blood flow?
