Question

During labor, certain hormones are released that cause the contraction of the uterus in order to push the baby out. When those hormones are sensed by the glands of the endocrine system, they secrete more of that hormone which keeps labor going until the baby is born. Which type of feedback loop is occurring?

1) Positive feedback loop
2) Negative feedback loop
3) Neutral feedback loop
4) No feedback loop

Answer 1

During labor, a positive feedback loop occurs. The hormone oxytocin is released, causing the uterus to contract and push the baby toward the cervix. The stretching of the cervix signals the release of more oxytocin, intensifying the contractions until the baby is born.

Step-by-step explanation:

A positive feedback loop is occurring during labor.

The hormone oxytocin is released during childbirth, which signals the uterine muscles to contract.

This contraction pushes the fetus toward the cervix, causing it to stretch.

The stretching of the cervix then signals the pituitary gland to release more oxytocin, leading to intensified labor contractions.

This positive feedback loop continues until the baby is born, and then the release of oxytocin decreases.
