blood sugar levels. The baby pushes against the cervix, causing it to stretch. a. Positive Feedback Response b. Negative Feedback Loop c. Both the choice is correct d. Neither a and b are correct Uterus Oxytocin causes the uterus to contract. Stretching of the cervix causes nerve impulses to be serit to the brain. 23. What type of feedback loop is shown Figure A? Umbilical - Cervix cord a. Negative b. Positive c. Neutral d. None of the choices The brain stimulates the pituitary to release oxytocin. Figure A Hypothalamus 24. What type of feedback loop is shown Figure B? Nerve impulses sent to skin a. Negative b. Positive c. Neutral d. None of the choices Thermoreceptors Increased sweating vasodilation Increase in body tomperature Decrease in bedy temperature Normal bedy temperture ar C) Nomal bedy mpertue arC) No change 25. When the level of carbon dioxide in the blood is Decrease in body temperature Increase in body temperature too high, the excess carbon dioxide reacts with water and produces carbonic acid. The carbonic acid causes the blood pH to become more acidic. When the blood pH becomes too acidic, chemoreceptors in the brain instruct the body to react and maintain homeostasis in blood pH. Which of these responses by the body would eliminate the excess carbon dioxide and help maintain homeostasis in the blood pH? Thermoreceptors Shivering. vasoconstriction Nerve impulses sent to skin tethalamun Figure B
