4. Explain the negative feedback system shown in Figure 4. Figure 4 5. During lactation (milk production), the suckling by the baby stimulates the production of oxytocin, which in turn causes contraction of smooth muscle surrounding the milk duct, causing milk to flow. The flow of milk increases the suckling by the baby and more oxytocin is produced. (a) Identify the feedback system described above. (b) What would end the feedback loop?
