Which of the following is an example of negative feedback? during birthing contractions, the hormone oxytocin is released and acts to stimulate further contractions. when a baby is nursing, suckling leads to the production of more milk and a subsequent increase in the secretion of prolactin, which in turn stimulates lactation. after a blood vessel is damaged, signals are released by the damaged tissues that activate platelets in the blood; these activated platelets release chemicals that activate more platelets. when blood glucose concentration increases, the pancreas produces and releases the hormone insulin, which decreases blood glucose. as blood glucose decreases, the rate of production and release of insulin decreases
