A patient is diagnosed with thyroid cancer later had her thyroid gland removed explain why this person was prescibed calcium and hormone supplementation?
Calcium (and vitamin D) are necessary to prevent hypocalcemia secondary to hypoparathyroidism, that is, a low level of of calcium in the blood (very serious) due to insuffient parathyroid hormone levels (parathyroid hormone functions to increase blood levels of calcium).

How is blood calcium regulated by the endocrine system?
Blood calcium levels are regulated by the hormones parathyroid hormone (PTH) and calcitonin. PTH is released by the parathyroid glands in response to low blood calcium levels and acts to increase blood calcium levels by promoting its release from bones and increasing absorption in the gut. Calcitonin, produced by the thyroid gland, works to decrease blood calcium levels by promoting its deposition in bones.
Explain the importance of the integumentary system to bone formation?
Production of Vitamin D - Some of the ultraviolet light striking the skin passes through the melanin sunscreen and causes a chemical change in the blood leading to the formation of vitamin D. This vitamin is required for the body to absorb calcium from the intestine. Calcium is essential for the development of teeth and bones.
Explain how nonsteroid hormones may function through an increase intracellular calcium ion concentration?
Non steroid hormones cannot diffuse freely through the cell membrane, therefore they interact with membrane receptors. There are many different types of receptors, many of which result in an increase in cellular [Ca2+], and increased cellular [Ca2+] can have a myriad of effects including cytoskeleton restructuring, muscle fibre contraction, regulation of calcium-dependent enzymes, action potential generation, secretion of vesicles, and even apoptosis. The increase in cellular [Ca2+] can be caused by as simple as the opening of a ligand(hormone)-gated calcium channel. Another far more complex, but somewhat more common pathway involves the hormone binding to a G-protein coupled receptor or a receptor tyrosine kinase, causing the receptor to activate an enzyme called PLC (phospholipase C) that will cleave a membrane phospholipid (phosphatidylinositol bisphosphate, PIP2) into two components (Inositol triphosphate, IP3, and Diacylglycerol, DAG). IP3 localizes to the endoplasmic reticulum and releases sequestered Ca2+, and DAG provides an anchor for another enzyme, PKC (protein kinase C). Anchored PKC is activated by the released Ca2+ and it begins to perform its duty, which is to add a phosphate group onto specific substrates, activating or deactivating them, causing a general shift in cellular dynamics.
What did Darwin use to explain evultion?
Darwin used the theory of natural selection to explain evolution. Natural selection is the process by which organisms best adapted to their environment tend to survive and pass on their genetic traits to offspring. This concept helps to explain how species gradually change over time, leading to the diversity of life we see today.
Explain how calcitonin and triiodothyroninne work together to meet the genetically determined maximum height at which an individual will grow during a growth spurt?
Calcitonin and triiodothyronine are hormones that regulate bone growth. Calcitonin lowers blood calcium levels by inhibiting bone breakdown, while triiodothyronine stimulates bone growth. Together, they help maintain proper bone density and growth during a growth spurt, keeping the individual within their genetically determined maximum height potential.
Explain why calcium hydroxide can be used in this way?
Calcium hydroxide is used to test for carbon dioxide because the product of the reaction, calcium carbonate, is insoluble, and easily visible.
Is calcium carbonate element or compound explain?
Calcium carbonate is a compound composed of the elements calcium, carbon, and oxygen. It is not an element itself but a combination of different elements bonded together in a specific ratio and structure.
Calcium carbonate has a formula CaCOз. Explain what this formula means?
Calcium carbonate has a formula CaCOз. Explain what this formula means?Anwer :CaCO3 means that for each molecule of it, it has one atom of Calcium, one atom of Carbon and 3 atoms of Oxygen.
How do I explain this hypothesis 'The higher the amount of calcium hydroxide added the more the pH will increase'?
Calcium hydroxide has a low solubility in water yet if the concentration of hydroxyl ions increase the pH increase.
Why would a calcium channel blocker lower Cardiac Output?
One of the factors that make muscles contract is the release of calcium onto the muscle fibers. An electrical signal is sent into the muscle and stimulates the sarcoplasmic reticulum to release calcium along the muscle. A calcium channel blocker may reduce the muscle's contact with calcium and could possible explain why the heart has lower output.

Why order calcium gold and iron was discovered?
The discovery of the order of elements calcium, gold, and iron is attributed to their differing reactivities. Calcium is more reactive than gold and iron is less reactive than both. This reactivity trend helps explain why these elements were discovered in that particular order historically.
