Question

Hormones that regulate mineral (salt) levels include:

a. Aldosterone
b. Parathyroid hormone (PTH)
c. Calcitonin
d. All of the above

Answer 1

Aldosterone, parathyroid hormone (PTH), and calcitonin are hormones that regulate salt levels in the body.

Step-by-step explanation:

The hormones that regulate mineral (salt) levels include:

1. Aldosterone: regulates sodium concentrations in urine, sweat, the pancreas, and saliva. It is stimulated by decreased blood sodium ion concentrations, blood volume, or blood pressure, or increased amounts of blood potassium.
2. Parathyroid hormone (PTH): regulates calcium and phosphate levels in the blood. It is released or synthesized in response to low blood calcium levels.
3. Calcitonin: helps regulate calcium concentrations in body fluids. It inhibits osteoclast activity in bones and stimulates excretion of calcium in the kidneys.
