Parts of Endocrine System Regulated by Feedback Loops

Example of Negative Feedback in Body
high blood sugar levels
pancreas cells alerted
pancreas secretes insulin into blood
insulin allows cells to absorb sugar
blood sugar level drops
brain tells pancreas to stop releasing insulin
pancreases releases glucagon
glucagon releases sugar into blood

Example of Positive Feedback in Body
2. Collagen in vessels trap platelets in blood
3. Platelets release clotting factors in blood
1. Damaged blood vessel
4. Clotting factors cause more platelets to get trapped in collagen
5. Platelets release more clotting factors
6. Get a blood clot
