Question

Complete each sentence describing the hormonal control of calcium homeostasis. Labels can be used more than once. decrease increase osteoblasts osteoclasts When levels of blood calcium _____, parathyroid hormone is released from the parathyroid glands located on the posterior side of the thyroid gland. Parathyroid hormone causes an increase in the number of _____ and greater rates of bone resoprption. As a result of direct actions on the target cells of the bone and kidneys parathyroid hormone works to _____ blood calcium levels. When blood levels of calcium _____, calcitonin is released from cells in the thyroid gland. Calcitonin causes an increase in the number of _____ and greater rates of bone deposition. As a result of direct actions on the target cells of bone and kidneys, calcitonin works to _____ blood calcium levels.

Explanation / Answer

Parathyroid hormones is release whenever ther is low calcium level in body regulating calcium level in body and absorbing calcium from diet

2) Osteoclasts

Parathyroid hormone causes osteoclast and greater resorption of calcium,

3) Decreases

Parathyroid hormone decreases releases calcium level in urine by absorbing maximum calcium from urine.

3) Decreases

Clacitonin hormone regulate the level of calcium whenever there is more calcium in our body it acts on kidneys by which low amounts of calcium is reabsorbed and larger of calcium Is release in urine and calcium level decreases calcitonin level also decreases.

4) Osteoblasts

By osteoblasts process calcitonin helps in formation and mineralization of bones.

5) Decreases

Calcitonin decreases the blood calcium levels by releasing more amount of calcium in urine.
