Calcium levels in the body are maintained by hormones. If the blood calcium level rises above a set point, calcitonin is secreted by the thyroid gland and sets into motion responses to lower the blood calcium back to the set point. If the blood calcium level falls below a set point, the parathyroid gland secretes parathyroid hormone that sets into motion responses to raise the blood calcium. These homeostatic responses are examples of
a. positive feedback
b. effectors
c. sensors
d. negative feedback

Respuesta :

Answer:

positive feedback

Explanation:Because when you get motion that means its positive but if doesn't feel motion than that is negative.

Calcium is the most abundant mineral in the body and is essential for the development of bones and teeth. The calcium levels in the body are maintained by the thyroid gland and hormones.

These homeostatic responses are examples of:

Option D. Negative feedback

This can be explained as:

  • When there is a change in a function and causes the output to decrease and vary the process is called negative feedback.

  • The body receptors sense a change in the calcium level brings about necessary alterations to counteract the situation.

  • The endocrine like the thyroid gland secretes parathyroid hormone when the calcium decreases. While calcitonin reduces the excess of calcium in the body.

Therefore, calcitonin and parathyroid balances the calcium levels and is negative feedback.
