In comparison, for the 2001 year the trust generated $2,939,731 in income, and donated $3,285,050 to the Watchtower. The difference between income and expenditure is made up by realising gains on the assets held. The income of the trust is from two main sources.
Parathyroid Glands: Essentials. 1  Parathyroid hormone regulates the bodyâs calcium levels. 2  There are four parathyroid glands, and they are each about the size of a grain of rice.3  Though theyâre located near each other, the parathyroid glands are not related to the thyroid gland. PTH regulates how much calcium is absorbed from your diet, how much calcium is excreted by your kidneys, and how much calcium is stored in your bones. 2  We store many pounds of calcium in our bones, and it is readily available to the rest of the body at the request of the parathyroid glands.
The two most important hormones for maintaining calcium levels in the body are parathyroid hormone (PTH) and 1,25(OH)2D (the active form of vitamin D). The major regulator is PTH, which is part of a negative feedback loop to maintain [Ca ++ ] ECF (see Humoral regulation).he role of PTH is to stimulate the regulated kidney enzyme, resulting in the production of 1,25(OH) 2 D. This is extremely important for bone health and Ca ++ homeostasis because 1,25(OH) 2 D works in the small intestine to promote Ca++ absorption.
