B1.28 The principles of homeostasis and how this links to maintaining the functions within the
physiological systems which contributes to maintaining a healthy body:
• principles of homeostasis:
o receptors
o effectors
o feedback systems
o role of nervous system
o role of the endocrine system
• how homeostasis contributes to maintaining a healthy body:
o maintains stability and function of the physiological systems and cells when there are changes
to internal and external conditions that would otherwise prevent enzymes from functioning
normally
B1.29 The normal expected ranges for physiological measurements and the factors which may affect
these measurements:
• normal expected ranges for physiological measurements:
Physiological measurements
Normal expected range for an adult
aged 19 to 65
blood pressure
systolic mmHg:90–120
diastolic mmHg:60–80
heart rate 60 to 100 beats per minute (bpm)
respiratory rate
at rest 12 to 20 breaths per minute
(bpm)
temperature 36 to 37.5°C
• factors that contribute to measurements outside of normal parameters:
o age
o weight
o exercise
o sex
o overall health
