When I was 13 years old in my 9th grade English class, we were assigned a theme: What I Want To Be When I Grow Up. From early on in life, all that I ever imagined I would be was an interior designer. So, that theme was easy for me.
PTH stands for parathyroid hormone. It is a protein hormone released by the parathyroid gland. The parathyroid glands are located in the neck, near or attached to the back side of the thyroid gland.Parathyroid hormone controls calcium, phosphorus, and vitamin D levels in the blood and bone.Release of PTH is controlled by the level of calcium in the blood.Low blood calcium levels cause increased PTH to be released, while high blood calcium levels block PTH release.t is a protein hormone released by the parathyroid gland. The parathyroid glands are located in the neck, near or attached to the back side of the thyroid gland.
The main target organs where parathyroid hormone exerts its effects are the bones and the kidneys. When needed, parathyroid hormone is released by the parathyroid glands into the blood and causes the bones to release calcium and increase levels in the bloodstream. It also causes the kidneys to stop calcium being lost in urine as well as stimulating the kidneys to regulate vitamin d metabolism (see below).
