__________________ feedback is the most common type of feedback in living systems because it brings levels back to normal. Counteracting the original stimulus.

• Negative

• Positive

• Neutral

• Osmosis

__________________ is the process in which the blood vessels get smaller, decreasing blood flow and keep heat from being released.

• Vasoconstriction

• Vasodilation

• Thermoregulation

• Positive Feedback

___________________ is the process in which the blood vessels get bigger, blood flow is increased, and heat is released.

• Vasoconstriction

• Vasodilation

• Thermoregulation

• Sweating

The body maintains a constant internal environment by using _________________ feedback (immediately tries to reverse the stimulus and bring it back to normal)

• Constructive

• Negative

• Positive

• Destructive
