Q

any deviation from the set point is made ____ or is _____

A

smaller or is resisted

17
Q

MECHANISMS OCCUR WHEN THE INITIAL
STIMULUS FURTHER STIMULATES THE RESPONSE

A SPECIAL CASE

A

POSITIVE FEEDBACK

18
Q
  • SYSTEM RESPONSE CAUSES PROGRESSIVE DEVIATION AWAY FROM
  • SET POINT, OUTSIDE OF NORMAL RANGE
  • NOT DIRECTLY USED FOR HOMEOSTASIS
  • SOME POSITIVE FEEDBACK OCCURS UNDER NORMAL CONDITIONS
A

POSITIVE FEEDBACK

19
Q

stretching of uterine walls causes contractions that further stretch the walls (continues until birthing occurs)

A

childbirth

20
Q

child feeding stimulates milk production which causes further feeding (continues until the baby stops feeding)

A

lactation

21
Q

the dominant follicle releases estrogen which stimulates LH and FSH release to promote further follicular growth

A

ovulation

22
Q

platelets release clotting factors which cause more platelets to aggregate at the site of injury

A

blood clotting
