GENERAL HISTOLOGY

Detailed explanation-1: -The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal.

Detailed explanation-2: -3 – Positive Feedback Loop: Normal childbirth is driven by a positive feedback loop. A positive feedback loop results in a change in the body’s status, rather than a return to homeostasis. The first contractions of labor (the stimulus) push the baby toward the cervix (the lowest part of the uterus).

Detailed explanation-3: -Feedback And Homeostasis : Example Question #4 Explanation: The only example of a positive feedback loop is labor contractions, since in that case, the output increases the original stimulus. In all of the other answer choices, the body is trying to maintain homeostasis by reversing the effect of the original stimulus.

Detailed explanation-4: -Oxytocin is one of a few hormones that have a positive feedback loop. This means that the release of oxytocin leads to actions that stimulate your pituitary gland to release even more of it.

Detailed explanation-5: -Example 1: Fruit Ripening. Example 2: Childbirth. Example 3: Blood Clotting. Example 1: Temperature Regulation. Example 2: Blood Pressure Regulation (Baroreflex) Example 3: Osmoregulation. Looking for Biology practice? 01-Mar-2022
