The hormone calcitonin is controlled by a negative feedback mechanism because it's release leads to the decrease of calcium blood levels.

<h3>What is negative feedback mechanism?</h3>

A negative feedback mechanism is the defined as a type of regulatory mechanism in the body where by the increased output of a system leads to a decrease of another system.

Therefore, the release of the hormone calcitonin (increased level of calcitonin in the blood) will lead to decrease in blood levels of calcium.

Give the definition of parasympathetic nervous system?
SashulF [63]

Answer: Autonomic nervous system is made up of 3 divisions; Sympathetic nervous system, parasympathetic nervous system and sympathetic division. All these divisions are involuntary actions where parasympathetic is ultimately responsible for the "rest and digest" part of it. When the body is at rest the parasympathetic nervous system inhibits or lowers high energy requiring bodily functions.

This nervous system will lower any fight or flight response actions such as the release of epinephrine into the blood and enable digestion, urination and defeacation. When engaged in digestion you feel relaxed and at rest, this is solely due to the parasympathetic nevous system.
