Quizplus · Accepted Answer

Calcitonin and parathyroid hormone (PTH) are the hormones that regulate calcium levels in the body. Calcitonin decreases calcium levels, while PTH increases calcium levels. T3 and T4 are thyroid hormones that regulate metabolism, oxytocin and prolactin regulate reproduction and lactation respectively, and insulin and glucagon regulate glucose levels in the body. Melatonin and glucocorticoids are hormones that regulate sleep and stress responses respectively and are not involved in calcium regulation.
