This is due to the deficiency of parathormone and is also called parathyroid hormone. It is produced by the parathyroid glands that are located in the neck near the thyroid gland. This hormone helps in the role of regulating the levels of calcium and phosphate in the blood. If the calcium level is low in the blood, more parathormone is released into the bloodstream. They maintain the level of calcium by bone resorption, increasing the absorption of calcium from the intestine and decreasing the level of calcium that is excreted.

Match the hormone with its site of production:
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
The human endocrine system is a messenger system that balances or controls distant target organs through feedback loops of hormones released by the internal glands of an organism right into the circulatory system. The hypothalamus is the neural control node for all endocrine systems, in invertebrates.
The endocrine system controls a variety of body functions through hormone release. Hormones are built by the endocrine system's glands and pass throughout the bloodstream to various organs and tissues in the body. Hormones then command these organs and tissues about how to act.
The Endocrine System is in charge of the following bodily functions:
