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.

What is a feedback mechanism in the skeletal system?

A feedback mechanism in a the skeletal system includes the bone narrow allowing calcium level to increase

What is the positive and negative ions if calcium chloride?

The positive ion in calcium chloride is calcium (Ca2+), while the negative ion is chloride (Cl-).

What is the definition of negative feedback?

Negative feedback is a regulatory mechanism in which a system responds to a change by initiating processes that reverse the change, bringing the system back to its set point or original state. It helps maintain stability and homeostasis in biological systems by dampening or counteracting changes.

What is the positive and negative ion for calcium oxide?

The positive ion in calcium oxide is the calcium ion (Ca^2+), which has lost two electrons. The negative ion in calcium oxide is the oxide ion (O^2-), which has gained two electrons.

What parts of the calcium chloride are attracted to what parts of the water molecule?

The positive calcium ions in calcium chloride are attracted to the negative oxygen atom in the water molecule, while the negative chloride ions are attracted to the positive hydrogen atoms in the water molecule.

Is calcium oxide a positive or negative ion?

Calcium oxide is a compound composed of calcium (Ca) and oxygen (O) ions. Calcium has a 2+ charge, while oxygen has a 2- charge. Therefore, calcium oxide is made up of a positive calcium ion (Ca2+) and a negative oxide ion (O2-).

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.

How do you write the positive ion and negative ion for CaS?

The positive ion for CaS is Ca^2+ (calcium ion) and the negative ion is S^2- (sulfide ion).

Is calcium the most abundant negative ion in extracellular fluid?

No, chloride is the most abundant negative ion in extracellular fluid, not calcium. Calcium is an important cation in the body and plays a role in various physiological processes, but it is not the most abundant negative ion in extracellular fluid.

How is the bonding in calcium oxide different from the bonding in sodium chloride?

calcium is mdonating one electron to each chloride. This makes the calcium a positive charge and the chloride a negative charge. This is called ionic bonding (CaCl2)

Does calcium form a negative ion?

No, calcium typically forms a positive ion (Ca2+) because it tends to lose two electrons to achieve a stable electron configuration.
