Hormones are typically broken down by enzymes in the liver or removed by the kidneys and excreted in urine. Additionally, hormones can also bind to specific receptors on target cells, initiating a response and reducing their concentration in the blood. Therefore, the persistence of hormones in the blood is limited to maintain balance and prevent overstimulation of target tissues.

When calcium blood levels fall a gland in the body releases a special hormone?
When calcium blood levels fall, the parathyroid gland releases parathyroid hormone (PTH). PTH helps regulate calcium levels in the blood by increasing calcium absorption in the gut, reabsorption in the kidneys, and releasing calcium from bone.
What is the target organ of ACTH?
The target organ of adrenocorticotropic hormone (ACTH) is the adrenal glands. ACTH stimulates the adrenal glands to produce and release cortisol, a hormone involved in the body's stress response.
What hormone increased the amount of glucose in the bloodstream?
Amylin
What organ releases hormones which regulate blood glucose levels?
The pancreas releases hormones, including insulin and glucagon, which help regulate blood glucose levels. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, while glucagon raises blood sugar levels by stimulating the release of glucose from storage in the liver.
Which hormone stimulates osteoclasts in the raising of calcium levels in the blood?
If you are looking for the one hormone that does this, then the answer is parathyroid hormone (PTH), produced in the parathyroid glands.A more technical description is given below:Three hormones act in the body to increase blood calcium levels to normal. These hormones are 1,25-Dihydroxycholecalciferol, parathyroid hormone (PTH), and calcitonin that originate respectively from the liver and kidneys, parathyroid glands, and thyroid glands. The first, 1,25-Dihydroxycholecalciferol (active vitamin D3), serves to increase calcium absorption from the intestine. The second, PTH, dissolves bone into the blood. The third, calcitonin, prevents the bone-derived calcium from being resorbed ("reabsorbed") into the bone from which it came via PTH. To summarize, these three hormones act in concert to raise calcium levels via external and internal routes.References: Ganong's Review of Medical Physiology, 23eKim E. Barrett, et. al.

Why is the persistence of hormone in the blood so limited?
Because you touch yourself.
How is erythropoietin carried through the body?
It is a hormone. So mainly by blood
How does aldosterone get to the kidneys?
Aldosterone is a hormone, so it gets to the kidneys via the blood stream.
What is hormone responsible for?
Tetany is caused by a disturbance of the blood calcium level. So you can say vitamin D (also considered a hormone) plays a role in it. Also, the parathyroid hormone level has a direct effect on calcium levels.
What hormone dilates bronchioles increases heart rate?
There is not an actual hormone which increases blood pressure. However, the hormone adrenaline is secreted by the pituitary gland and has the effect of speeding up the contraction of the heart muscle. In turn this leads to increased blood pressure due to Fick's Law. The stroke volume of the heart has increased so more blood is being forced through the network of blood vessels
When both ovary are removed from rat then which hormone is decreased in blood?
When both ovaries are removed from a rat, the hormone that is decreased in the blood is estrogen. The ovaries are responsible for the production of estrogen, so their removal leads to a decrease in estrogen levels in the bloodstream.
What hormone is responsible for tetany?
Tetany is caused by a disturbance of the blood calcium level. So you can say vitamin D (also considered a hormone) plays a role in it. Also, the parathyroid hormone level has a direct effect on calcium levels.
Why are leydig cells located close to the capillaries?
because they are hormone-secreting and so they have to be in close contact with blood vessels
What hormone is excreted by the parathyroid glands and regulates calcium levels in the blood and tissues?
Parathyroid hormone (PTH) is excreted by the parathyroid glands and plays a crucial role in regulating calcium levels in the blood and tissues. It does so by increasing the release of calcium from bone, enhancing calcium absorption in the intestines, and promoting calcium reabsorption in the kidneys.
How does the body replace blood lost blood when injury has occurred?
The plasma is replaces in the short term by releasing ADH (Anti-Diuretic Hormone) into the blood streem. This hormone makes the body hold onto more water so the body can put it into the plasma. The red blood cells are replaces over time by the bone marrow of the larger bones.
When calcium blood levels fall a gland in the body releases a special hormone?
When calcium blood levels fall, the parathyroid gland releases parathyroid hormone (PTH). PTH helps regulate calcium levels in the blood by increasing calcium absorption in the gut, reabsorption in the kidneys, and releasing calcium from bone.
Are hormones used to treat diabetes?
Diabetes is when your body does not produce the hormone insulin. So with someone with type 1 diabetes they have to do daily insulin injections. So the job of insulin is to level out your blood sugar level so yes the hormone insulin is used to treat diabetes.
