foundation physiology Flashcards
1
Q
formula for pulse pressure
A
systolic-diastolic
2
Q
formula for MAP
A
TPR x CO
3
Q
what is the cause of S4
A
high pressure in the ventricle and therefore the atria has to squeeze extra hard to get blood into the ventricle
(S4 = atrial contraction)
4
Q
normal variation in body temp
A
36-37.5 degrees celsius
5
Q
diurnal variation in body temp
A
0.6 degrees higher in the late afternoon
6
Q
what is the temp change associated with menstruation
A
1 degree higher post ovulation
7
Q
4 types of energy transfer
A
- conduction - loss of heat via touch
- convection - loss of heat via movement of air/fluid across surface
- radiation
- evaporation - release of energy as fluid converted to vapour
8
Q
what is the temperature acclimitization that occurs in hotter climates
A
- sweating occurs sooner
- sweat volume increases
- sweat Na decreases
9
Q
what molecule causes fever
A
PGE2
