#Unit 7. System Physiology – Animal
  1. Aspirin inhibits the cyclooxygenase enzyme, necessary for the synthesis of prostaglandins. By inhibiting the production of prostaglandins, aspirin interrupts the pathway that pyrogens utilize to decrease the set-point temperature.
  2. Aspirin activates the cyclooxygenase enzyme, necessary for the synthesis of prostaglandins. By inhibiting the production of prostaglandins, aspirin interrupts the pathway that pyrogens utilize to raise the set-point temperature.
  3. Aspirin inhibits the cyclooxygenase enzyme, necessary for the synthesis of prostaglandins. By inhibiting the production of prostaglandins, aspirin interrupts the pathway that pyrogens utilize to raise the set-point temperature.
  4. Aspirin inhibits the cyclooxygenase enzyme, necessary for the synthesis of prostaglandins. By stimulating the production of prostaglandins, aspirin interrupts the pathway that pyrogens utilize to raise the set-point temperature.
