Parathyroid hormone promotes which of the following?
A
Increase in blood sodium levels
B
Decrease in blood glucose levels
C
Decrease in blood potassium levels
D
Increase in blood calcium levels
Verified step by step guidance1
Understand the role of parathyroid hormone (PTH) in the body. PTH is secreted by the parathyroid glands and plays a crucial role in regulating calcium levels in the blood.
Recognize that PTH increases blood calcium levels by stimulating osteoclasts, which are cells that break down bone tissue, releasing calcium into the bloodstream.
Note that PTH also enhances the reabsorption of calcium in the kidneys, reducing the amount of calcium excreted in urine.
Understand that PTH promotes the activation of vitamin D in the kidneys, which increases intestinal absorption of calcium from the diet.
Conclude that the primary effect of parathyroid hormone is to increase blood calcium levels, not sodium, glucose, or potassium levels.
