The parathyroid gland is the major regulator of blood Ca levels. When the Ca levels in the blood decrease, the parathyroid gland releases more parathyroid hormone. This in turn increases osteoclasts which results in more bone breakdown. this releases more Ca into the blood stream. When Ca levels in the blood increase the thyroid gland releases Calcitonin. this decreases the activity of the osteoclasts which in turn decrease the levels of Ca in the blood.

What is the negative feedback interaction between calcitonin and parathormone?
Calcitonin and parathyroid hormone (PTH) have opposing effects on calcium levels in the body. Calcitonin decreases blood calcium levels by inhibiting bone breakdown and promoting calcium excretion by the kidneys, while PTH increases blood calcium levels by stimulating bone breakdown and enhancing calcium uptake from the intestines and kidneys. This interaction helps to maintain calcium homeostasis in the body.
Parathyroid glands is a negative or positive feed back?
The parathyroid glands are involved in negative feedback regulation of blood calcium levels. When blood calcium levels are low, the parathyroid glands release parathyroid hormone (PTH) to increase calcium levels by stimulating calcium release from bones, absorption from the intestines, and reabsorption from the kidneys. Once calcium levels are restored, the release of PTH is inhibited, demonstrating negative feedback control.
How does the regulation of blood calcium concentration exemplify negative feedback and homeostasis?
The regulation of blood calcium concentration involves a negative feedback loop where sensors detect changes in calcium levels, triggering responses to bring it back to the normal range. Homeostasis is maintained by the concerted action of hormones like parathyroid hormone and calcitonin, which help regulate calcium balance in bone, kidneys, and the intestines. When blood calcium levels rise, these hormones work to decrease calcium absorption to restore balance, exemplifying the principle of negative feedback in maintaining homeostasis.
What chemical causes a decrease in the blood calcium level?
Calcitonin is a hormone that can cause a decrease in blood calcium levels by promoting its uptake and storage in bones. It works in opposition to parathyroid hormone, which increases blood calcium levels.
Which is greater when blood calcium levels when parathyroid hormone is increased or decreased?
Blood calcium levels are greater when parathyroid hormone is increased. Parathyroid hormone helps regulate calcium levels in the blood by promoting its release from bones and increasing its absorption from the intestines, leading to higher blood calcium levels.
What is an example of a negative feedback in human body?
example of negative feedback example of negative feedback
Is an amplifier a negative feedback?
Yes, Amplifire have negative feedback.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
What is negative feedback of a closed loop system?
Negative feedback is a feedback where it is used in negative side in a closed loop system.Such as a inverting side feedback in op-amp.
What are examples of feedback loops in are body?
Examples of feedback loops in the body include the regulation of blood sugar by insulin and glucagon, the maintenance of body temperature through sweating and shivering, and the control of breathing rate in response to changing oxygen levels. These feedback loops help maintain homeostasis and keep our body functioning properly.
What kind of feedback is used in emitter follower?
emitter follower is a type of negative feedback ,
What kind of feedback mechanism is it when it causes the initial stimulus to decline?
Negative feedback mechanism.
