Solution

Parathyroid hormone has several direct effects in the body:

  1. Promotes calcium reabsorption by the kidneys: This is a direct effect of parathyroid hormone. It increases the reabsorption of calcium by the kidneys, reducing the amount of calcium excreted in the urine.

  2. Promotes activity of osteoclasts: This is another direct effect of parathyroid hormone. It stimulates the activity of osteoclasts, which are cells that break down bone tissue. This process releases calcium into the bloodstream.

  3. Enhances general cellular metabolic rates: This is not a direct effect of parathyroid hormone. The hormone primarily affects calcium homeostasis and bone metabolism.

  4. Activates vitamin D in the kidneys: This is a direct effect of parathyroid hormone. It stimulates the conversion of inactive vitamin D into its active form in the kidneys. Active vitamin D increases calcium absorption in the intestines and promotes bone health.

  5. Decreases blood calcium levels: This is not a direct effect of parathyroid hormone. In fact, the hormone works to increase blood calcium levels, not decrease them.

So, the direct effects of parathyroid hormone in the body are:

  • Promotes calcium reabsorption by the kidneys
  • Promotes activity of osteoclasts
  • Activates vitamin D in the kidneys

What hormone causes the blood calcium level to increase by activating vitamin D in the kidneys to aid in the reabsorption of calcium? A. Parathyroid B. Calcitonin C. Mineralcorticoids D. Glucocorticoids

Effector: Synergistically, PTH and calcitriol (vitamin D) increase low blood calcium levels. Osteoclast activity is stimulated by PTH, which promotes bone release and resorption of calcium into the blood (Khan et al., 2022). Furthermore, PTH stimulates the kidneys to convert vitamin D from inactive to active form, calcitriol. This will encourage calcium absorption in the small intestine, increasing blood calcium levels. Together, these mechanisms elevate calcium levels in the blood and restore calcium homeostasis. Increased calcium levels in the serum act as a negative feedback loop, signalling the parathyroid glands to stop the release of PTH is this statement correct?
