Positive and negative feedback
aldosterene
Calcitonin
Parathyroid hormone (PTH) and calcitonin regulate blood calcium levels. PTH increases the calcium concentration in the blood, and calcitonin decreases it.
When calcium levels increase, parathyroid hormone decreases. When calcium levels decrease, parathyroid hormone increases. This is known as a negative feedback system.
calcitonin
Negative feedback is a process in which the body's hormones regulate and maintain homeostasis, or a state of equilibrium. This process is used to maintain stable internal conditions within the body, such as temperature, water balance, blood sugar levels, and hormone levels. Negative feedback occurs when hormones are released into the bloodstream, which then triggers an opposite response from the body to counteract the initial action. This is an example of how negative feedback controls the body's hormone levels. For example, when a hormone is released into the bloodstream, it can trigger the release of a second hormone that will inhibit or reduce the production of the first hormone. This is an example of negative feedback, as the second hormone acts as an inhibitor to the first hormone, which helps to maintain balanced hormone levels in the body. Additionally, some hormones can act as stimulators, meaning they can increase the production of another hormone, which will then reduce its own production. This is another example of negative feedback, as the stimulus hormone is stimulating the production of another hormone, which then helps to reduce its own production. In order to maintain a state of equilibrium, the body needs to be able to identify when the hormone levels are too high or too low and respond accordingly. Hormones can be regulated through a variety of mechanisms, including negative feedback, which is one of the most important ways in which the body regulates its hormone levels. Negative feedback helps to ensure that the body's hormones are kept in balance, which helps to maintain homeostasis.

Parathyroid hormone (PTH) and calcitonin regulate blood calcium levels. PTH increases the calcium concentration in the blood, and calcitonin decreases it.
Controlled largley by negative feedback, when hormone levels rise, signals are transmitted to the endocrine organ, releasing the hormone, telling the organ to decrease the amount of hormone released.
When calcium levels increase, parathyroid hormone decreases. When calcium levels decrease, parathyroid hormone increases. This is known as a negative feedback system.
