Feedback Mechanism

Front (Question)

Feedback Mechanism consists of (2)

Back (Answer)

• Positive Feedback Mechanism • Negative Feedback Mechanism

Front (Question)

Decrease in the product; Increases the activity of the system and the production rate

Back (Answer)

Positive Feedback Mechanism

Front (Question)

Increase in the product decreases the activity of the system and the production rate

Back (Answer)

Negative Feedback

Front (Question)

• Each Hormone is produced in a specific Endocrine gland • Hormones are released into blood circulation and carried to site of action as FREE hormone or bound to transport protein • Each hormone acts at a specific site (target organs) to induce certain characteristics, biochemical changes
