Guida verificata passo dopo passo1
Understand the role of Parathyroid Hormone (PTH): PTH is a hormone secreted by the parathyroid glands that plays a crucial role in calcium homeostasis.
Recognize the primary function of PTH: PTH increases blood calcium levels by stimulating osteoclast activity, which breaks down bone tissue and releases calcium into the bloodstream.
Clarify the misconception: PTH does not increase calcium deposition in bones; instead, it promotes the release of calcium from bones to increase blood calcium levels.
Consider the physiological context: When blood calcium levels are low, PTH is released to restore balance by increasing calcium availability in the blood.
Conclude with the correct statement: The statement 'PTH increases Ca2+ deposition in the bones' is false because PTH actually facilitates the release of calcium from bones.
