Homeostasis Feedback Loops

Contractions during childbirth When a contraction occurs, the hormone oxytocin is released into the body, which stimulates further contractions. This results in contractions increasing in amplitude and frequency.

Blood Clotting The loop is initiated when injured tissue releases signal chemicals that activate platelets in the blood. An activated platelet releases chemicals to activate more platelets, causing a rapid cascade and the formation of a blood clot.

Breast feeding During lactation the more the baby suckles, the more milk is produced, via a surge in prolactin secretion.
