    • NSAIDS

• Positive vs Negative Feedback

• Pitocin is an agonist of the oxytocin receptor

  • given if birthing process does not proceed properly

Antidiuretic Hormone ( ADH )

• Increase in ADH release

  • Increase in $H_{2}O$$H_2O$ transport into the blood

    • Decreases blood osmolarity

• Decrease in ADH release

  • Decrease in $H_{2}O$$H_2O$ transport into the blood

    • Increase in blood osmolarity

1. Dehydration or eat a lot of food
2. Blood osmolarity increases
3. Increases ADH release
4. $H_{2}O$$H_2O$ is transported into the blood
5. Blood osmolarity decreases

1. Over-hydration or starvation
2. Blood osmolarity decreases
3. Decrease in ADH release
4. Decreases $H_{2}O$$H_2O$ transport into the blood
