Multiple Choice

Which of the following effects is NOT associated with parathyroid hormone (PTH)?

Promotes activation of vitamin D

Increases blood calcium levels

Decreases calcium reabsorption in the kidneys

Stimulates osteoclast activity

Verified step by step guidance

Understand the role of parathyroid hormone (PTH) in the body. PTH is crucial for maintaining calcium homeostasis.

Recognize that PTH primarily acts to increase blood calcium levels. It does this by stimulating osteoclast activity, which breaks down bone and releases calcium into the bloodstream.

Identify that PTH promotes the activation of vitamin D. Active vitamin D increases calcium absorption from the gut, further contributing to higher blood calcium levels.

Consider the effect of PTH on the kidneys. PTH increases calcium reabsorption in the kidneys, preventing calcium loss in urine, thus maintaining higher blood calcium levels.

Evaluate the statement 'Decreases calcium reabsorption in the kidneys.' Since PTH actually increases calcium reabsorption in the kidneys, this effect is NOT associated with PTH.
