, In a postive feedback mechansims the initial response of the effector
enhances the original stimulus so that further responses are even greater.
Positive feedback causes the variable to change in the same direction of
the initial changes causing the variable to deviate further and further from
homeostatsis
positive feedback mechanisms control rare events and they set off a linked
sequence of events. Once initiated the results of each reaction feed into
the next like a series of waterfalls on a river and because of this postive
feedback often referred to as cascades that amplify the original stimulus.
examples of postive feedback
- Contractions during labour: Oxytocin is a hypothamlamic hormone that
intensifies labour contractions during the birth of a baby ocytoncic causes
the contractions to become both more frequent and more powerful. The
increased contractions cause more oxytocin to be released, which causes
more contractions, and so on until the baby is born. The birth ends the
stimulus for oxytocin release and shuts off the positive feedback
mechanism.
- Blood clotting: Once a vessel has been damaged, platelets immediately
begin to cling to the injured site and release chemicals that attract more
platelets. This rapidly growing pileup of platelets temporarily "plugs" the
tear and initiates the sequence of events that finally forms a clot

- male and female gonads (Testis, Scrotum, Prostate, Ductus deferens)
(Mammary glands (in breasts), ovary, uterus, vagina, , uterine tube.)
The overall function of the reproductive system is produces gametes that
unite to form a new organism; release hormones that regulate reproduction
and other body processes
