Answer:
Option A) Oxytocin causes the uterus to contract ,further stimulating the receptors that signal the brain to release oxytocin.!
Explanation:
Positive feedback is a mechanism in which the output of a process increases the magnitude of the process which caused that output and this loop continues.
The most common example of the Positive Feedback Mechanism is the child birth. During child birth, the child pushes on the walls of uterus. This stimulates the pressure receptors which send signals to brain to release oxytocin. This oxytocin causes the wall of uterus to contract further, which is again detected by the pressure receptors. This sends signals to the brain again and this process continues in this loop.
There's six main functions of the skeletal system
1 - Support
Provides structural support for the entire body.
2 - Protection
Surrounds soft tissue- ex. ribs and sternum protect the heart and lungs, - skull protects the brain.
3 - Movement
Skeletal muscle is attached to bone so it pulls on the bone when it contracts.
4 - Mineral homeostasis
Stores calcium and phosphorus--minerals are released into the blood when needed.
5 - Blood cell production
Red bone marrow produces red blood cells, white blood cells and other blood elements.
6 - Storage
Storage of minerals and lipids(fats)---yellow marrow stores fat --(found in long bones).
