Which of the following is an example of a negative feedback control system?
A) During birth, the baby's head presses against the cervix and stretches it;
stimulating the release of oxytocin; oxytocin causes contractions of muscles
in the uterus; this pushes the baby against the cervix harder, increasing the
stretch of the cervix.
OB) Loss of water through perspiration while hiking in the desert decreases the
amount of water in the blood; decreased levels of water in the blood
stimulate the release of ADH from the posterior pituitary; ADH causes the
kidneys to reabsorb water from the urine; blood levels of water increase;
levels of ADH decrease.
C) Four hours after lunch blood glucose levels start falling; low blood glucose
levels stimulate the release of glucagon, glucagon causes the liver to break
down glycogen into glucose and release it into the blood; blood glucose
levels rise; no more glucagon is released.
OD) A and B (but not C)
E) B and C (but not A)
