all of the above

if the body failed to produce and secrete the thyroid hormones, the result would be

Parathyroid

Identify the organ that responds to an initial stimulus of calcium being below the normal range

PTH

Identify the hormone secreted in response to a stimulus below the normal range

Bones release stored calcium

Identify one of the target cells/organs for the hormone in part b and its resulting effect.

The thyroid gland

Identify the organ that responds to the initial stimulus of calcium being above the normal range.

Calcitonin

Identify the hormone secreted in response to a stimulus above the normal range.

The target organ is the kidneys and the effect is they release excess calcium in to the urine

Identify one of the target cells/organs for the hormone in part E and its resulting effect.
