Which hormone is secreted in response to low levels of calcium in the bloodstream?

Thyroid hormone

Parathyroid hormone

Calcitonin

Vasopressin

Answer and Explanation

The Correct Answer is B

Parathyroid hormone (PTH) is a hormone produced by the parathyroid glands, which are located behind the thyroid gland in the neck. PTH regulates the calcium levels in the blood by stimulating the release of calcium from the bones, increasing the absorption of calcium from the intestines, and decreasing the excretion of calcium from the kidneys. When the calcium levels in the blood are low, PTH is secreted to raise them back to normal.

Correct Answer is C

Explanation

Acidosis is a condition where the blood's pH is lowered due to an excess of H+ in the body. This can occur due to metabolic causes, such as diabetes, kidney failure, ingestion of toxins, or respiratory causes, such as hypoventilation or lung disease. The body has several mechanisms to compensate for acidosis and restore the normal pH balance. One of them is to increase the rate and depth of breathing, which helps to remove CO2 from the body and reduce the formation of H2CO3.
