Anatomy and Physiology Assignment Research project: The role of calcium and vitamin D in the development and maintenance of bone structure What is Parathyrin? Parathyrin is a substance made by the parathyroid gland that helps the body store and use calcium. A higher than normal amount of parathyrin causes high levels of calcium in the blood and may be a sign of disease. Parathyrin is also sometimes known as Parathormone‚ parathyroid hormone and PTH. What is Calcatonin? Calcatonin is a hormone

mechanical restitution is driven by calcium movement and concentrations. An increase in cystolic calcium concentration causes contraction in myocardium. Calcium from the extracellular fluid enters the cardiomyocyte through the L-type Ca2+ channels after being propagated by the cardiac action potential which depolarises the cell. This flood of calcium triggers more calcium release from the sarcoplasmic reticulum via Calcium-Induced Calcium Release (CICR). Calcium binds to the ryanodine receptor on

Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

Determining the Ksp of Calcium Hydroxide by Titration of Saturated Ca(OH)2(aq) with HCl(aq) Abstract: Titration is a technique that has been used in this experiment to identify the Ksp value of calcium hydroxide in order to determine the extent to which the compound is soluble in water. A known volume of 50 mL of hydrochloric acid‚ a concentration of 0.05 M hydrochloric acid‚ a volume of 50 mL calcium hydroxide base‚ an unknown concentration

Investigating How Concentration of Acid Affects the Reaction Between Calcium Carbonate and Hydrochloric Acid Introduction ============ According to the collision theory temperature‚ concentration‚ surface area and catalysts all affect rates of reaction as shown in the diagrams below. Increasing any of these should increase the number of collisions and so increase the reaction rate up to an optimum point. Increasing the temperature causes the particles to collide with more
