Question 14 (1 point) During exercise, blood pressure increases. The body responds by attempting to lower blood pressure to maintain homeostasis and regulate blood pressure to safe levels.

Which statements about feedback systems are correct? A negative feedback system tends to decrease the stimulus that affects it. A positive feedback loop, involving the kidney, maintains blood homeostasis. A positive feedback system would be unable to maintain homeostasis, since it would be unable to maintain any type of equilibrium. An example of how the body uses a positive feedback system to maintain body temperature is the release of sweat onto the surface of the skin. A feedback system requires coordination between the sensory receptors, an integrator center, and an effector.

Glucose levels in the blood are regulated by two hormones, insulin and glucagon. If the blood glucose drops below the normal range, the pancreas produces glucagon, which causes breakdown of glycogen in the liver, increasing blood glucose levels. This is an example of: sensors. negative feedback. positive feedback. effectors.

Which of the following scenarios can be classified as a negative feedback loop? a increase in blood pressure to reduce heart rate b increase in testosterone to help increase a fight-or-flight response c increase in oxytocin caused by increased contractions d increase in platelet production to help increase blood clotting
