Which hormone increases calcium and phosphate ion absorption by the intestines?

Parathyroid hormone (PTH)

Explanation:

Parathyroid hormone's main function is to promote calcium absorption in the intestine to reach calcium homeostasis (equilibrium) in the body. It is produced in the Parathyroid hormone which is actually four small glands located in the neck, next to the thyroid gland.

it takes hundreds of years to become stable.

if you have another question lmk.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
