The hormone released in response to low blood calcium levels is?
parathyroid hormone (PTH) is released in response to low blood calcium levels. It acts to increase calcium levels by promoting calcium release from bones, increasing calcium absorption in the intestines, and reducing calcium loss in the kidneys.
What are the four conditions in a cell that must be kept in homeostatic balance?
The four conditions in a cell that must be kept in homeostatic balance are temperature, pH levels, concentrations of ions (such as calcium, potassium, and sodium), and levels of nutrients and waste products. Maintaining these conditions within a narrow range is crucial for the cell to function properly.
What hormone is released when blood calcium levels are too high?
When blood calcium levels are too high, the hormone calcitonin is released. Calcitonin helps regulate calcium levels by promoting its deposition into bone tissue, thus lowering blood calcium levels.
How is blood calcium regulated by the endocrine system?
Blood calcium levels are regulated by the hormones parathyroid hormone (PTH) and calcitonin. PTH is released by the parathyroid glands in response to low blood calcium levels and acts to increase blood calcium levels by promoting its release from bones and increasing absorption in the gut. Calcitonin, produced by the thyroid gland, works to decrease blood calcium levels by promoting its deposition in bones.
What hormone controls levels of calcium in blood and helps maintain balance of phosphorus?
Parathyroid hormone (PTH), released by the parathyroid gland; and calcitonin, released by the thyroid gland, control the levels of phosphorus in the body. Most of the phosphorus in the body is stored in the form of phosphate (PO4) attached to calcium in the skeletal systems to form calcium phosphate [Ca3(PO4)2]. When PTH is released, excess phosphate is released into the urine and calcium is released from the skeletal system into the bloodstream. The calcitonin plays its part by helping form calcium phosphate molecules, where they become part of a mineral matrix in the bone. Because of the relationship between PTH and calcitonin, calcium and phosphate maintain proportionally inverse levels in the blood.

Why is osteoporosis considered to be a homeostatic imbalance?
It weakens bones and fractures them

What is released when calcium levels drop?
carbon dioxide
Why is calcitonin released?
To reduce the amount of calcium and phosphates in the blood without augmenting calcium accretion.
What hormone is released when blood calcium levels are too high?
When blood calcium levels are too high, the hormone calcitonin is released. Calcitonin helps regulate calcium levels by promoting its deposition into bone tissue, thus lowering blood calcium levels.
When blood calcium levels fall what doesn't occur?
When blood calcium levels fall, the body does not increase the secretion of calcitonin, a hormone that lowers blood calcium levels. Instead, the parathyroid hormone (PTH) is released, which works to raise calcium levels by stimulating the release of calcium from bones, increasing calcium reabsorption in the kidneys, and enhancing the absorption of calcium in the intestines. Therefore, calcitonin's role is not activated during low calcium levels.
What is calcitonin released from?
Calcitonin is released from the C cells (also known as parafollicular cells) in the thyroid gland. It helps regulate calcium levels in the blood by decreasing calcium levels when they are too high.
What does the onset of tetanus indicate about the amount of free calcium in the sarcoplasm?
At tetanus levels of released Calcium in the the intracellular compartment are at their highest level.
Under which condition can pastures be responsible for milk fever in dairy cows?
An excess amount of calcium-rich plants like alfalfa can cause milk fever because blood calcium levels can be quickly decreased enough that the cow is unable to draw calcium from her bones to make up for the decreased levels, causing her to go into depression due to very low blood calcium levels.
