Question

1/30 - homeostasis feedback (dg)
determine whether the following example is positive (+) or negative feedback (-) and name the body system(s) that are involved.
the suckling action of a newborn causes the mother to produce a hormone called prolactin which leads to milk production. more suckling leads to more prolactin, which in turn leads to more lactation.
which type of feedback does this loop show?
which body systems are involved?

Explanation:

1. Positive feedback amplifies the original stimulus; here, suckling triggers more prolactin, which leads to more milk production and more suckling, creating an amplifying cycle.
2. The endocrine system produces and regulates hormones like prolactin, while the nervous system detects the suckling stimulus and signals hormone release.

Answer:

1. Type of feedback: Positive feedback (+)
2. Involved body systems: Endocrine system, Nervous system
